The Pythagorean Theorem

Here you will find an animation demonstrating the Pythagoren theorem.

The animation starts with one right angle triangle with hypothenuse
c and cathetes a and b.

Then, 3 copies are created and arranged within a square of side length
a+b.

The arrangement leaves an area of c² uncovered within the boundaries
of the square.

Then the 4 triangles are rearranged and the uncovered area is seen
to be a²+b².

Since moving around the triangles does not changed the total uncovered
area, we see that
c²=a²+b²
