I lost the track of original ideas there, but one could make a project that looks like the attached picture also to avoid the square root. (After setting the "origin-at-center" switch of the Playfield.) But maybe that was not what they want to do. They later want to move on to non-square cases. The following Etoys project doesn't provide the proof of theorem, but you can type numbers at "w = ..." and "h = ..." and press the "goAround" button. It shows the length of the diagonal. http://dev.laptop.org/~yoshiki/etoys/Pythagoras.001.pr
