Given that ∆mtw ≅ ∆cad, which angles are corresponding parts of the congruent triangles?

∠m ≅ ∠a

∠m ≅ ∠d

∠m ≅ ∠c

I believe the answer is the last one ∠M  ≡ ∠C. for triangles which are congruent the corresponding angles are equal while the corresponding sides are equal.
Therefore, if three pairs of sides of two triangles are equal in length (SSS), then the triangles are congruent. In addition if two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent.

The answer would be c
