In the given figure ΔBAC = ΔQRP by SAS criterion of congruence. In congruency postulates, SSS, SAS, ASA, and AAS, three quantities are tested, whereas, in hypotenuse leg (HL) theorem, hypotenuse, and one leg are only considered, that too in case of a right triangle. Prove that $$ \triangle LMO \cong \triangle NMO $$ Advertisement. B = E & C = F (Hint: Remember when you learned how to copy an angle?) This is possible only if P is coincides with A Case 3: If AB < DE (The included side is the side between the vertices of the two angles.)
