Pythagorean Theorem

A little applet allowing students to explore things about the Pythagorean Theorem, specifically:
  1. Does it always hold for all right-angled triangles?
  2. Does the length of the sides matter?
  3. Will it ever hold for triangles other than right-angled triangles?
... and it comes with a graphical proof of the theorem too.
