Geometry will give brainliest the congruency of triangle mno and triangle xyz can be proven using a reflection across the line bisecting. 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.

Given two triangles mno and xyz  with < m-=< x, < n-=< y and yo-=nz. the triangles are deduced to be congruent by aas (angle-angle-side) postulate which states that if there exists two corresponding angles and at least one side which is corresponding to a set of a given figure, then the figures are congruent.therefore we can conclude that mno and xyz are congruent by aas

I’d say letter a..
