Question

Which describes how to find all rotation angles less that 360° that will map a regular polygon onto itself?

Answer 1

This question is about rotations of polygons.

To rotate a polygon onto itself, we need to know the exact rotation we have to do. This rotation depends on the type of polygons, specifically, the number of sides.

To know the exact angle rotation to map the polygon onto itself, we have to divide 360° by the number of sides.

Therefore, the right answer is the third choice.
