If the figure undergoes a series of rotations, which statement is true?
O The resulting figure will always be congruent to the original because rotations are rigid transformations that preserve angle measures and side lengths.
O The resulting figure will never be congruent to the original because rotations are non-rigid transformations that do not preserve angle measures.
O The resulting figure will never be congruent to the original because rotations are non-rigid transformations that do not preserve side lengths.
O The resulting figure will sometimes be congruent to the original because rotations are rigid transformations that preserve angle measures and side lengths.
