No, my maths is just fine. There's a separate 3:4:5 one (with the squares on those sides being the 9 + 16 = 25 with which you are presumably familiar). This one has sides which are √2 by √3, giving a diagonal of √5 (ie the squares on them are 2 + 3 = 5). Part of my point was that the sides themselves don't have to be simple integers.

Your math is fuzzy. Did you maybe mean 3:4:5?
