Question

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

Explanation:

Rigid transformations mapping congruent triangles include translation, rotation, reflection, or combinations. Reflection reverses orientation, and if the image is not overlapping, translation adjusts position. The triangles likely require reflection to reverse orientation and translation to align positions.

Answer:

B. reflection then translation
