a five-reptile

what are the proportions for the lengths of sides of a right angled triangle if five of them (all congruent) make up a triangle similar to the original?



















thanks to John Golden (math hombre) for pointing out that this forms the basis of the aperiodic 'pinwheel' tiling by John Conway
