figure abcd below is transformed to obtain figure a′b′c′d′:

a coordinate grid is shown from negative 6 to 6 on both axes at increments of 1. figure abcd has a at ordered pair negative 4, 4, b at negative 2, 2, c at negative 2, negative 1, d at negative 4, 1. figure a prime b prime c prime d prime has a prime at ordered pair 4, 0, b prime at 2, negative 2, c prime at 2, negative 5, d prime at 4, negative 3.

part a: write the sequence of transformations that changes figure abcd to figure a′b′c′d′. explain your answer and write the coordinates of the figure obtained after each transformation. (6 points)

part b: are the two figures congruent? explain your answer. (4 points)
