Question

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

Hello,
I suppose the picture of A is A', of B is B'.
|AB|=|A'B'|
Rotations keep the distances.
