Pythagorean Theorem applies to all Right Triangles

This shows scaled right triangles with their squared sides on top and their squared hypotenuse on the bottom. This is an easy demonstration to students that no matter how large or small the right triangle is, the pythagorean theorem still applies. Whenever I learn mathematics concepts, it is hard for me to visualize them on a larger scale. The goal of this applet would be to help students visualize this as right triangles increase in size.

As the triangle changes in size, do the two top lines stay equal lengths?

What angles could you change in the original triangle ABC and the top lines still remain the same length?
