Two rigid transformations are used to map trianglejkl to trianglemnq. the first is a translation of vertex l to vertex q. what is the second transformation?

a rotation about point L

Explanation:

In rigid transformations, the lengths of the sides of the original figure are preserved in the new figure, making Triangle MNQ congruent to Triangle JKL.

So, if the first is a translation of vertex L to vertex Q, then a rotation about point L must continue, so that, Triangle MNQ is congruent to Triangle JKL.
