Question

I know is between a and C can someone please help me

Answer 1

For a regular polygon, the rotation about its center that keeps the polygon unchanged is:

`(360)/(n)\text{ degrees rotation}`

where n is the number of sides of the polygon.

In this case, n=6, therefore, a 360/6=60° clockwise rotation about the center of the hexagon would result ina hexagon with the same vertices.
