Two rigid transformations are used to map TriangleABC to TriangleQRS. The first is a translation of vertex B to vertex R. What is the second transformation?

a reflection across the line containing AB
a rotation about point B
a reflection across the line containing CB
a rotation about point C

Triangles A B C and Q R S are shown. Sides A B and Q R are congruent. Angles C A B and R Q S are congruent. Angles Q S R and A C B are congruent.

Rotation about point B.

Reason: After the translation B → R, B is fixed at R, so the second rigid motion must pivot the translated triangle about that point to carry A to Q and C to S. A rotation about B (now at R) accomplishes this; the reflections listed would fix the wrong points.
