Which statement is true about figures abcd and a'b'c'd? (1 point)

a. they are congruent, because a'b'c'd' is obtained by translating abcd up by 5 units and
then reflecting it about the y-axis.

b. they are similar, because a'b'c'd'is obtained by rotating abcd counterclockwise
degrees about the origin and then reflecting it about the y-axis.

c. they are congruent, because a'b'c'd' is obtained by translating abcd up by
then reflecting it about the x-axis.

d. they are similar, because a'b'c'd' is obtained by rotating abcd counterclockwise by 90
degrees about the origin and then reflecting it about the x-axis.
