Simulating Geometric Theorems Using Etoys
View the video below to see how to use the Etoys project to simulate the theorem.
Run and upload the Etoys project at http://squeakland.org/launcher/?http://squeakland.org/content/showcase/everyone/accounts/rcaton/theorem1.003.pr. Make sure you have Etoys installed on your computer. Check your proof of the theorem and try the challenges.
