exists and is an alternate of . LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
They have one right angle, and that's the definition of right triangles. Let's also state that we're given that MN is congruent to ZY and NO is congruent to YX. Okay, right triangles and congruent hypotenuses and congruent legs. Now we can state that triangle MNO is congruent to triangle ZYX using the HL theorem.
