Proving the Pythagorean Theorem Using Similarity

The video tutorial explains how to prove the Pythagorean theorem using triangle similarity. It begins with a review of altitudes and the angle-angle postulate, then outlines a series of steps to demonstrate the theorem. The process involves cutting triangles, drawing altitudes, and arranging them to write proportionality statements. Finally, algebra is used to solve for variables and complete the proof, showing that a squared plus b squared equals c squared.
