Question

m A = 50, AB = 12, m E = 56, m R = 50, RS = 12, ST = 16, MN = 12, m S = 56, DE = 12, EF = 16, and m D = 50. Which pair of triangles are congruent?

Answer 1

Does that question come with a figure? If so, please post it.

Answer 2

\[\triangle mDE\] and \[\triangle mRS\].

The ordering of the letters is important.
