Question

the triangles are congruent by sss.
which transformation(s) can be used to map one triangle onto the other? select two options.
□ reflection only
□ translation only
□ dilation, then translation
□ rotation, then translation
□ rotation then dilation

Explanation:

Congruent triangles (SSS) preserve size/shape, so dilation (changes size) is invalid. The diagram shows triangles can map via reflection alone (over a line) or rotation then translation (rotate one triangle to align orientation, then shift to overlap).

Answer:

reflection only, rotation, then translation
