A reflection across the line containing ZK.

Reason: Z and K lie on line ZK so they stay fixed under that reflection, and M and Q lie on the line through Z perpendicular to ZK (both KZ M and KZ Q are right angles), so M and Q are mirror images across ZK. Thus the reflection across ZK maps triangle MZK to triangle QZK.
