#### A Geometric Proof of the Pythagorean Theorem

Students will see an animated presentation of the proof of the Pythagorean Theorem. This animated PowerPoint presentation uses shearing and the invariance of the area of triangles with congruent bases and heights to show a step-by-step geometric proof of the…
