Caption: An animation giving a visual proof of the Pythagorean theorem.
Proof explicated:
The visual proof is NOT complete. One actually has to assume that one has a 2-dimensional Euclidean space with the properties of such a space. For further explication, see, e.g., Roger Penrose, The Road to Reality, 2004, p. 25--33).
