Mathematicians, check my work

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)

am i right?

part a: the sequence of transformations would be reflection across the y-axis followed by a translation 3 units down.

once reflected, coordinates are:
a- (4,4)
b- (2,2)
c- (2,-1)
d- (4,1)

part b: yes, they are congruent. they have the same shape and size, coordinates alike also.
