Question

dentifying rigid transformations
the triangles are congruent by the sss congruence theorem.
which transformation(s) can map \\( \triangle lmn \\) onto \\( \triangle l ^ { prime } m ^ { prime } n ^ { prime } \\)?
rotation then translation
reflection only
translation only
reflection then translation

Explanation:

• A reflection changes the orientation of a figure. Looking at the two triangles, we can see that their orientation is different initially.
• A translation then moves the reflected figure to the exact position of the target triangle.

Answer:

reflection then translation
