If you rotate a line 180° it’ll be the same line but the endpoints will be swapped because you’re just flipping it over. This means they are the same in length, while they’re in the same position essentially, this is the only answer that fits because it’s not perpendicular, E‘ F‘ is not half the length of EF,And it’s not greater than twice the length either. This means your answer is answered number two, E’F’ and EF are the same length.
