| Abstract: | Many teachers and textbooks mention ‘three and a half basic congruence theorems: SAS, ASA, SSS and HL for right triangles. Why do they neglect the SSA theorem? A recent article [1] investigated the SSA theorem, but it seems necessary to extend and, in one point, to correct the result given there. |
