Part 2: Use congruency theorems to prove congruency.
The congruency of AMNO and AXYZ can be proven using a reflection across the line bisecting
OZ. However, this congruency can also be proven using geometric postulates, theorems, and
definitions. Prove that the triangles are congruent using a two-column proof and triangle
congruency theorems.
