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 have the same shape and size. Dilations change the size of a figure, so options involving dilation (c and e) are incorrect. A translation moves a figure without rotation or reflection, and a reflection flips a figure over a line. A rotation - then - translation or a reflection can map one congruent triangle onto another.

Answer:

A. reflection only
D. rotation, then translation
