Question

what is the final transformation in the composition of transformations that maps pre - image ghjk to image ghjk?
a translation to the right
a reflection across line m
a 90° rotation about point g
a 180° rotation about point g

Explanation:

By observing the orientation of pre - image GHJK and image G'H'J'K', the final step is a reflection over line m. The shape's position and orientation relative to line m indicate this transformation.

Answer:

a reflection across line m
