M is the midpoint of AD.

Triangles A B M and D C M are connected at point M. Sides A B and C D are congruent. The lengths of sides B M and M C are 27.

What single transformation is required to map one of these congruent triangles onto the other?

Reflection
Rotation
Translation
Dilation

Rotation.

A 180° rotation about point M sends A to D (M is the midpoint of AD) and sends B to the point on the opposite ray with MB = MC (BM = MC = 27), so triangle ABM maps exactly to triangle DCM.
