Use the following information for the next two questions.

a series of rigid motions was performed to transform quadrilateral abcd to result in quadrilateral a'''b'''c'''d'''.

(check image attached)

identify the series of transformations needed to map quadrilateral a'b'c'd' to quadrilateral abcd. be sure that you describe how to move quadrilateral a'b'c'd', while quadrilateral abcd remains stationary.

transformation #1:
transformation #2:
transformation #3:

part b:
explain why quadrilateral abcd and quadrilateral a'b'c'd' are congruent in terms of rigid motions.
