The pentagon can be turned in five ways without changing how it looks:
- 0° (no turn),
- 72° (shift one point),
- 144° (shift two points),
- 216° (shift three points),
- 288° (shift four points).
These rotations just rearrange the points but keep the pentagon's shape the same. Since there are five points, there are five different rotations that keep the pentagon looking the same.
