Proof of Pythagoras's Theorem by Shearing
2015-10-12 11:36
This applet visually proves the Pythagorean theorem using geometric shearing. By constructing a right triangle and squares on its sides, it uses vectors and rotations to show area invariance under shear transformations. This verifies that the sum of the squares of the legs equals the square of the hypotenuse, offering an intuitive tool for geometry education.
