Comment Comment by einpoklum That looks like "half" of the proof using a square:https://www.onlinemathlearning.com/image-files/xpythagorean-...where you draw three extra triangles, not just one, and they surround a square of c x c. Think about it as making two copies of the trapezoid, one rotated on top of the other. parent einpoklum 11 months ago
