...may be proved that the square ACGF is equal to the parallelogram KCLM. So ABDE+ACGF the sum of the squares =BKLH+KCML, the sum of the two parallelograms or square BCMH; therefore the sum of ihe squares on AB and AC is equal to the square on BC. QED* Cor. 1. Hence the hypothenuso of a right-angled... | |
