Answer

Explanation:

Step1: Analyze translation result

After translating vertex B to vertex R, we need to align the rest of the triangle.

Step2: Consider rotation effect

A rotation about point C can adjust the orientation of △ABC to match △QRS. A reflection across a line (either containing AB or CB) won't correctly align the triangles in most cases, and rotation about point B is not the correct way to map the triangles.

Answer:

a rotation about point C
