Answer:
B.
Explanation:
The angles on each triangle have to match each other when comparing them. The order matters. In answer B, angle M matches with angle R, angle D matches with angle B, and angle Q matches with angle S. The 2 different angle symbols in one triangle with one and two rings are to represent which angle they correspond to in the other triangle. For example, Angle B has two rings so it matches with angle D because it also has two rings. Angle M has one ring and matches angle R because angle R also has one ring.
