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′

Answer 1

The figure was simply rotated, the relative side lengths have not changed.

Length AB=Length A'B'

Answer 2

Length of AB=Length of A'B' because they are corresponding sides.
