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 jk a rotation about point l a rotation about point k a reflection across the line containing lk

Explanation:

Step1: Analyze rigid - transformations

Rigid transformations include translation, rotation, and reflection. After translating vertex L to vertex Q, we need to align the other parts of the triangles.

Step2: Check rotation and reflection

If we rotate about point L, we can align the two triangles. A reflection across a line may not map the triangles correctly as the orientation and position of the triangles suggest rotation is more appropriate. Rotating about point L can re - orient △JKL to match △MNQ after the translation of L to Q.

Answer:

a rotation about point L
