Question

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

Explanation:

A reflection is a transformation that flips a figure over a line. In this case, there is a line of symmetry (the line \(QN\)) that can map \(\triangle MNQ\) onto \(\triangle PQN\). A translation would slide the triangle without flipping it, which won't work here. A rotation - then - reflection or rotation - then - translation is more complex than needed. Since the triangles are mirror images across a line (implied by congruence and right - angle positions), reflection only is the correct transformation.

Answer:

reflection only
