Pythagorean Theorem Proof By Rearrangement

This animation demonstrates a classic visual proof of the Pythagorean theorem using four congruent right triangles arranged inside a square. By rearranging the triangles into two configurations within the same square, it shows that the area of the square on the hypotenuse equals the sum of the areas of the squares on the two legs. Useful for geometry students learning why a squared plus b squared equals c squared without algebraic manipulation.
