A regular pentagon has five equal sides and angles, and it can be rotated around its center in certain ways that make it look the same. There are five rotations that carry the pentagon onto itself: rotating by 0 degrees (no movement), 72 degrees, 144 degrees, 216 degrees, and 288 degrees. Each of these rotations moves the pentagon to a position where it looks exactly like it did before the rotation.
In 3sentences, summarize the rotations that carry a regular pentagon onto itself. (4 points)
