Draw geometric constructions with the help of Robocompass's animated features. View ideas from the example list to understand how the site works. Choose one of the examples (such as Bisect an Angle) then click the "Play All" button to follow the step-by-step procedure in action. Stop the animation at any point and resume play when ready. In addition to using examples provided, create your own constructions using commands found in the "How to" link. Robocompass interfaces with Google memberships, allowing you to SAVE animations! For a good overview of the site, choose "Take the Tour." (The tour button only shows AFTER you have clicked a sample file or "Open Robocompass.") This option offers a video overview and explanation. If your district blocks YouTube, "Take the Tour" may not be viewable. You could always view the video at home and bring it to class "on a stick" to share. Use a tool such as KeepVid reviewed here to download the video from YouTube. The tool states it operates best in Chrome and requires WebGL. You need to enable Web GL to use it in Safari. See directions how in this blog post. iOS and Android apps are "coming soon." Imagine this one on a tablet! Note: This site uses significant bandwidth to load the animations and the tour video. Be patient.

In the Classroom

If you cannot make this site work on the first try, try again. This one is worth getting tech help to make it work! Note: This site uses significant bandwidth to load the animations and the tour video. Pretest ON the devices(s) you will use in class before planning to use it for a lesson! Display Robocompass on your interactive whiteboard or projector to demonstrate geometric constructions. Provide a link on your class website or blog for students to view constructions at home. This site is perfect to excite your gifted students! Challenge students to create and share their own constructions for other geometric purposes such as transformations. Even art teachers may find this tool useful for demonstrating perspective and more.
