Polygon Transformer empowers students to explore geometric transformations with shapes that they design. Students input vertices as ordered pairs into a list, which are then plotted on a coordinate plane and connected with straight lines. The resultant polygons can then be transformed in any direction, reflected across horizontal and vertical lines, rotated around the origin and dilated to any scale. Vertices are labeled for each polygon, and the vertex values are optionally shown below the coordinate plane. The coordinate plane can be viewed at three different zoom levels to work well with all screen sizes, and each transformation can be reversed with a handy undo feature.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
