Question

which rigid transformation would map △mzk to △qzk? a rotation about point k a reflection across the line containing mz a reflection across the line containing zk a rotation about point z

Explanation:

Triangles MZK and QZK share side ZK. Reflecting △MZK across line ZK maps M to Q, as Z and K are on the reflection line (fixed), resulting in △QZK.

Answer:

C. a reflection across the line containing $\overline{ZK}$
