Scaling Triangles to Prove the Pythagorean Theorem
A viewer told me about this proof after watching my video about Ptolemy's Theorem ( • A Beautiful Proof of Ptolemy's Theorem. ). It's just a special case of that proof, but works well on its own. It doesn't seem to be well known; I finally found a reference to it as proof #41 on this page: https://www.cut-the-knot.org/pythagor...
Maybe I'll create a series of these videos with other lesser known proofs of the Pythagorean Theorem.
Note: this is a remake of a previously published video ( • Scaling Triangles to Prove the Pythagorean... ) which fixes some animation issues.
