Question

the triangles are congruent by the sss congruence theorem.
which transformation(s) can map △bcd onto △wxy?
○ rotation only
○ reflection only
○ translation, then rotation
○ translation, then reflection

Explanation:

First, observe the orientation of the two triangles. △BCD and △WXY have a mirrored orientation, which indicates a reflection is needed. Additionally, the triangles are in different positions, so a translation first moves △BCD to the general area of △WXY, followed by a reflection to match their orientation and map them exactly.

Answer:

translation, then reflection
