![]() Rotate pentagon QRSTU 90° counterclockwise to create pentagon Q’R’S’T’U’. Pentagon QRSTU is shown on the coordinate grid. Therefore, kite KLMN was rotated 180° about the origin to create kite K’L’M’N’. 180° clockwise and counterclockwise rotation: (x,y) becomes (-x,-y).Let’s look at the rules, the only rule where the values of the x and y don’t switch but their sign changes is the 180° rotation. Let’s start by identifying the coordinates of the vertices of kite KLMN and of our rotated kite:Ī closer look at the coordinates of the vertices shows that the coordinates of K’L’M’N’ are the same as the vertices of the original kite but with the opposite sign. Can you identify which rotation of kite KLMN created kite K’L’M’N’? ![]() The kite has been rotated about the origin to create the kite K’L’M’N’. Kite KLMN is shown on the coordinate grid. Now I want you to try some practice problems on your own. Let’s apply the rules to the vertices to create quadrilateral A’B’C’D’: To rotate quadrilateral ABCD 90° counterclockwise about the origin we will use the rule (x,y) becomes (-y,x). Let’s apply the rule to the vertices to create the new triangle A’B’C’: Let’s rotate triangle ABC 180° about the origin counterclockwise, although, rotating a figure 180° clockwise and counterclockwise uses the same rule, which is (x,y) becomes (-x,-y), where the coordinates of the vertices of the rotated triangle are the coordinates of the original triangle with the opposite sign. To rotate triangle ABC about the origin 90° clockwise we would follow the rule (x,y) → (y,-x), where the y-value of the original point becomes the new x-value and the x-value of the original point becomes the new y-value with the opposite sign. Now that we know how to rotate a point, let’s look at rotating a figure on the coordinate grid. 270° counterclockwise rotation: (x,y) becomes (y,-x)Īs you can see, our two experiments follow these rules.270° clockwise rotation: (x,y) becomes (-y,x).180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).90° counterclockwise rotation: (x,y) becomes (-y,x). ![]() 90° clockwise rotation: (x,y) becomes (y,-x).Lucky for us, these experiments have allowed mathematicians to come up with rules for the most common rotations on a coordinate grid, assuming the origin, (0,0), as the center of rotation. In our second experiment, point A (5,6) is rotated 180° counterclockwise about the origin to create A’ (-5,-6), where the x- and y-values are the same as point A but with opposite signs. In our first experiment, when we rotate point A (5,6) 90° clockwise about the origin to create point A’ (6,-5), the y-value of point A became the x-value of point A’ and the x-value of point A became the y-value of point A’ but with the opposite sign. Let’s take a closer look at the two rotations from our experiment. Here is the same point A at (5,6) rotated 180° counterclockwise about the origin to get A’(-5,-6). Let’s look at a real example, here we plotted point A at (5,6) then we rotated the paper 90° clockwise to create point A’, which is at (6,-5). If you take a coordinate grid and plot a point, then rotate the paper 90° or 180° clockwise or counterclockwise about the origin, you can find the location of the rotated point. ![]() Let’s start by looking at rotating a point about the center (0,0). Here is a figure rotated 90° clockwise and counterclockwise about a center point.Ī great math tool that we use to show rotations is the coordinate grid. We specify the degree measure and direction of a rotation. The angle of rotation is usually measured in degrees. The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. Another great example of rotation in real life is a Ferris Wheel where the center hub is the center of rotation. A figure can be rotated clockwise or counterclockwise. A figure and its rotation maintain the same shape and size but will be facing a different direction. We call this point the center of rotation. More formally speaking, a rotation is a form of transformation that turns a figure about a point. There are other forms of rotation that are less than a full 360° rotation, like a character or an object being rotated in a video game. The wheel on a car or a bicycle rotates about the center bolt. The earth is the most common example, rotating about an axis. Hello, and welcome to this video about rotation! In this video, we will explore the rotation of a figure about a point.

![]() Shortly after this, the actress appeared in an episode of Doctor Who, a role which saw her reunite with her St Trinian’s co-star David Tennant, and then The Three Musketeers alongside Matthew Macfadyen and Orlando Bloom. In 2009, aged 20, Wilde made her acting debut in the film St Trinian’s 2: The Legend of Fritton’s Gold, appearing alongside Rupert Everett, Colin Firth and Talulah Riley. “It was never a route I had expected to go down, but was something I found I was interested in.” “I still have friends who can’t understand how I could be an actress because normally I’m quite introverted,” she says. Having never even appeared in so much as a school play, this decision came as a surprise to her family and friends. Her next step was to enroll in a fine art course at City & Guilds of London Art School, but she wasn’t there long before realising she wanted to act. “I think you need to have a very strong personality to exist in that world and I wasn’t prepared for it.” “I stopped because it didn’t make me happy and I didn’t feel comfortable doing it,” she says. However, she rejected these labels and by 18, had decided to walk away from modelling. ![]() Wilde also caught the attention of the press, which attempted to brand her as an ‘It’ girl and named her the second most eligible girl in Britain. “I think you need to have a very strong personality to exist in the modelling world and I wasn’t prepared for it” I think I just got swept up in the ride of it all.” “I did a few shoots with Isabella Blow, which was amazing, then I met Naomi and she took me to her agency. “It was such a mad way to start within that industry,” she recalls. She joined Campbell’s agency, Premier Model Management, and the teenager soon found herself swept up in the frenzy of the fashion world, fronting campaigns for Burberry, Topshop and Abercrombie & Fitch. Describing herself as “incredibly shy” when she was younger, Wilde never considered acting, but at 14 was talent-spotted by Naomi Campbell. Her sister Isabella and ‘unofficial’ stepsister Cressida Bonas – while no blood relation, Bonas’ mother was once married to Wilde’s father – have similarly pursued acting careers. ![]() With both parents having children from previous marriages, the actress is blessed with many siblings: “I have hundreds of brothers and sisters, so my fondest memories are of growing up and playing with them in the country,” she says, smiling. Wilde changed her moniker when she became an actress (her agent suggested it after coming across Oscar Wilde’s name on her bookshelf), but otherwise remains very close to her family. Her mother, Vanessa Hubbard, was also a model when she was younger and sat for David Bailey CBE. She is the daughter of businessman John Anstruther-Gough-Calthorpe, former chairman of the Watermark Group and grandson of Sir Fitzroy Anstruther-Gough-Calthorpe, 1st Baronet. Wilde’s roots are similarly tied to English tradition and her family lineage can be traced back to Charles II. “I have hundreds of brothers and sisters, so my fondest memories are of growing up and playing with them in the country” It is one of those brands that I feel has such a long-standing history.” “My mum knows the brand for its jewellery and my dad for its silver. “I practically grew up with Mappin & Webb,” she comments. With her natural elegance and poise – no doubt born from her English aristocratic heritage – Wilde was the ideal choice for the jeweller, which has more than 241 years of history and a Royal Warrant that was first granted by Queen Victoria in 1897. Her most recent role as the brand ambassador of Mappin & Webb is more in line with Wilde’s work to date, having worked as a model before becoming an actress. And yet, this suggests that she is far more self-assured than many others in an industry that seems to be riddled with self-doubt and low self-esteem. Speaking to 27-year-old Wilde, her slightly reserved nature undoubtedly makes her come across as more reticent than some of her acting peers and she admits that she has never been one “to shout the loudest in the room”. However, having pursued two of the most competitive industries, modelling and acting, she is by no means timid, and for those of you who watched the second series of the BBC’s hit period drama Poldark, in which she plays the feisty Caroline Penvenen, you perhaps wouldn’t be surprised. Granted, with her angelic features and softly spoken voice, it would be an easy assumption to make. Despite first impressions, Gabriella Wilde is no shrinking violet.

I’ll describe the grid system in more detail later in this article.īootstrap has a number of UI components for creating a site’s UI, including Button dropdown, Button group, Dropdown, Navbar, Breadcrumb, Media object, Pagination and Progress bar, just to name a few. The most commonly used CSS classes involve the Bootstrap grid system, a collection of classes that organize the layout of a page using rows and columns. You can use the Bootstrap CSS classes to annotate HTML5 elements. Version 3 of Bootstrap comes with CSS classes that specifically target browser widths commonly found on mobile browsers, tablet browsers, desktop browsers and even browsers running on large desktop screens. It also allows you to easily customize the default behavior for a specific form factor while keeping your page looking good on other form factors. For this reason, performance should be an important consideration when designing, developing and testing pages that use any part of the Bootstrap framework.īootstrap does a lot for you automatically. Even though Bootstrap is considered lightweight, a Web page that uses Bootstrap tooling still requires more processing to render than a page written specifically for a given form factor. In other words, it uses CSS more than JavaScript to do its work. Bootstrap is considered a lightweight framework. The Bootstrap framework, like many other UI frameworks for Web development, is a collection of CSS classes, UI components and JQuery plug-ins. What Is Bootstrap?īootstrap is a responsive UI framework for building Web sites. I chose Bootstrap for this article because it has a solid level of adoption, is fully documented, and is included in the ASP.NET Web Application templates. It would be unfair to label one of these frameworks “the best” because there are different approaches and Web sites have different requirements. There are more than a dozen different UI frameworks on the market today. This created an environment for developers to take over.ĭevelopers love to make tools for other developers, and the mobile Web is no exception. Processors became faster, mobile browsers advanced to the point where they could display any Web page (even if the page hadn’t been designed for a mobile device), and bandwidth increased. While the standard for mobile Web markup was evolving, significant advances also occurred with hardware, mobile browsers and bandwidth. ![]() After a fitful start, beginning in 1998, in which Wireless Markup Language (WML), Compact HTML, and XHTML Mobile Profile surfaced and then disappeared, HTML5 finally became the next-generation HTML standard for all devices in 2009. It has taken a certain amount of evolution to bring the software industry to the point where a solution like Bootstrap emerges. After the overview, I’ll consider some factors that can help you decide if a framework like Bootstrap is right for your site. Bootstrap is a framework that enables responsive Web design (RWD)-an approach to designing Web sites that aims to provide an acceptable viewing experience across all form factors with a single code base. This article presents an overview of one of these tools, Bootstrap, which is included in many of the Visual Studio 2013 Web Application templates. Still, thought must be given to determine if one is right for your site. Though these tools aren’t a panacea for mobile Web developers, they can significantly ease the development process. ![]() Today, however, there are UI frameworks that allow a site’s Web pages to support mobile, tablet, desktop and even large-screen desktops-all with a single code base. In the past, a Web site that supported mobile and desktop required different code bases. What if that user could instead encounter a UX designed specifically for a mobile form factor, and enjoy easily interacting with your site? Will the user see a rendering of your site that’s impossible to use on a phone because the site was designed for desktop only? If so, that user will most likely move on to a more mobile-friendly site. It’s only a matter of time before a customer taps your site’s URL on their mobile device.
