Pythagorean Theorem V (visual proof; Leonardo da Vinci)

This is a short, animated visual proof of the Pythagorean theorem (the right triangle theorem) using the a diagram that is now attributed to Leonardo da Vinci. The proof uses reflection and rotation symmetry arguments. This theorem states the square of the hypotenuse of a right triangle is equal to the sum of squares of the two other side lengths. #mathshorts #mathvideo #math #pythagoreantheorem #pythagorean #triangle #manim #animation #theorem #pww #proofwithoutwords #visualproof #proof #leonardodavinci #davinci

01:30 I said something incorrect so made a small cut. I meant to say the two hexagons are made from congruent parts.

There is the Cut The Knot list that was linked on r/math in 2010.

I think this is my new favourite proof

Thanks! Nice proof and also nice to know who came up with it originally.
