A regular pentagon has symmetrical properties that allow it to be rotated and still coincide with itself. The rotations that carry a regular pentagon onto itself are:
- 0 degrees (or 360 degrees) - This is the identity rotation where the pentagon looks the same.
- 72 degrees - This rotation takes each vertex to the position of the next vertex.
- 144 degrees - This rotation moves each vertex two positions forward.
- 216 degrees - This rotation moves each vertex three positions forward.
- 288 degrees - This rotation takes each vertex four positions forward.
Thus, there are a total of 5 rotations (including the identity rotation) that carry a regular pentagon onto itself.
