In fact, can’t we generalise this further by dropping the requirement that ∠ACB be a right angle? Why the right angles at B C and D in Figure 9 ? The reason is that there are ❙D two components to the proof of the Pythagorean ✂❙ ❙ Theorem as represented in Figure 9 and only one is ✂ ❙ present in Figure 10. First, of course, is the instance, C✂ ❙A ABC = ADC + CDB, of the axiom asserting the Figure 10 whole is equal to the sum of its parts. Second, however, is the requirement that the polygons placed on the sides of the triangles be similar— and this clearly is not the case for the triangles that would be obtained from Figure 10 by reﬂecting ACD across AC, BCD across BC, and ACB across AB.
