Simulating Geometric Theorems Using Etoys
Theorem: If a radius of a circle bisects a chord that is not a diameter, then it is perpendicular to that chord.
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.
