A regular pentagon has 5 sides, and it can make 4 distinct turns onto itself before completing a full circle (360 degrees). These turns are determined by the angles between adjacent vertices, which can be described as rotations.
1. **Turns**: The number of turns a regular pentagon can make onto itself before coming around full circle is 5 turns (including the one full turn which is 360 degrees).
2. **Multiple of Degrees**: Each turn that results in the pentagon appearing identical to its original position corresponds to \( \frac{360}{5} = 72 \) degrees. Therefore, it can make turns of 72 degrees, 144 degrees, 216 degrees, and 288 degrees, in addition to the full turn (360 degrees).
3. **Symmetry**: Since a regular pentagon can make turns less than 360 degrees onto itself, it exhibits **rotational symmetry**. Specifically, it has rotational symmetry of order 5, meaning it looks the same at every \( 72 \) degrees of rotation around its center.
In summary:
- A regular pentagon can make **4 turns** onto itself before coming around full circle.
- Each of these turns is a multiple of **72 degrees**.
- It has **rotational symmetry** of order 5.
