Very well executed! The animation is fluid, the presentation is very elegant and conveys the reasoning exactly the same way I would go about proving it algebraically and reinforces neatly that the theorem holds for an arbitrary right triangle.
This is almost exact "proof" of Pythagorean Theorem I came up with once. Mine's not animation, just drawing I did in MS paint. Legs of my Δ are in ratio of 3:1. I measure Alan's to be 173:60, which is very close. My Δ is red, Alan's is yellow. My idea was you pivot upper-left Δ to join with upper-right, lower-left to lower-right. And that's it, problem solved. Alan took next step to shift horizontal triangles. Didn't think of that, but I was working with static drawing, not animation.

What's the piece?

Does it have to be a left triangle`?

it less than 60 seeing it starts @0:11 AND ENDS @0:58
