Wheel of Theodorus Extra Credit Project

This Wheel of Theodorus Extra Credit Project activity & project also includes:

Think it's possible to make a wheel out of triangles? According to this geometry project it is. Using their knowledge of the Pythagorean Theorem, young mathematicians carefully calculate and draw a series of right triangles that form together to make a pinwheel-like design. A great hands-on project for a middle school pre-algebra class!
