Use rigid motions to explain whether the figures are congruent. δabc is the pre-image. δa’b’c’ is the image. be sure to describe specific rigid motions in your explanation.

hint: there are two transformations represented, in a distinct order.

a specific description of the rigid motion would include the following information:

- translation: a description of vertical and horizontal change (the translation vector)

- reflection: identify the line of reflection in equation format

- rotation: identify the point of rotation, the direction, and degree of rotation
