Scaling Triangles to Prove the Pythagorean Theorem

A viewer told me about this proof after watching my video about Ptolemy's Theorem (https://youtu.be/ZK08Z5A9xH4). 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/pythagoras/index.shtml

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 (https://youtu.be/LSaUhB8RAKs) which fixes some animation issues.
