Pythagorean Theorem proof by translation

Total areas of the two squares are equal. The red area on the left equals c², while the red areas on the right sum to a² + b². This means that c² = a² + b², since the green and blue triangles are of equal size. Sliders a and b vary the size of the right triangle. Slider n will show the translation of triangles from the left square to the right.
