Which statement is true about figures abcd and a'b'c'd'? a'b'c'd' is obtained by translating abcd 4 units up and then reflecting it about the y-axis. a'b'c'd' is obtained by translating abcd 4 units right and then reflecting it about the x-axis. a'b'c'd' is obtained by rotating abcd counterclockwise by 180 degrees about the origin and then reflecting it about the y-axis. a'b'c'd' is obtained by rotating abcd counterclockwise by 90 degrees about the origin and then reflecting it about the x-axi
