Question

two rigid transformations are used to map △jkl to △mnq. the first is a translation of vertex l to vertex q. what is the second transformation? a reflection across the line containing lk a reflection across the line containing jk a rotation about point l a rotation about point k

Explanation:

Rigid - transformations include translations, rotations, and reflections. After translating vertex L to vertex Q, a rotation about point L will align the other vertices and sides of the triangles correctly. Reflections across the given lines won't map the triangles accurately as needed. Rotation about point K won't work as well as rotation about point L (the point that was already translated to match).

Answer:

a rotation about point L
