Pythagorean Theorem 1
... You know triangles cannot be proven congruent using “SSA” because that theorem does not exist. HOWEVER, consider the two RIGHT triangles ΔABC and ΔXZY. If C and Y are right angles, legs, AC = ZZ = 15 and hypotenuses AB XZ = 17, that is an SSA situation. But – aren’t these triangles congruent? W ...
