figure abcd is rotated by 180 degrees about the origin in the counterclockwise direction to obtain figure a′b′c′d′:
which statement best compares the lengths of the sides of the two figures?

length of ab = length of c′d′
length of cd = length of a′b
′ length of cd = length of b′c′
length of ab = length of a′b′
