Question

the triangles are congruent by sss or hl. which transformation(s) can map △pqr onto △stu? reflection, then translation rotation only rotation, then reflection translation only

Explanation:

To map △PQR onto △STU, we consider rigid transformations. Since congruent triangles may have orientation differences, reflection (to flip orientation) followed by translation (to reposition) is needed.

Answer:

A. reflection, then translation
