Thales's Right Angle Thm

This intended use is to have a tangible visual for Thales's Right Angle Theorem. This theorem states: Any angle inscribed in a semi circle is a right angle. When the center disk is rotated it shows that no matter where the top post is (ie. the point is on the semi circle), that the angle will always be a right angle. As someone in the education field, this is a powerful tool to share with students. Not only will students be able to prove the theorem, but they can see it in action and make the connection in many ways.
