Full solution stays hidden until you ask for it.
1. Divide 360 degrees by the number of sides.
2. Use that as the smallest positive rotation.
3. List multiples of that angle less than 360 degrees.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Listing only 360 degrees.
