Question

Deshawn draws a regular pentagon and rotates it about its center.

Which angle measures can Deshawn rotate the regular pentagon through to map it onto itself?


Select each correct answer.

Answer 1

72, 144, 216, 288, 360 degrees.

Explanation:

If we draw lines from the canter to each point on the pentagon the angles between the lines are 360 / 5 = 72 degrees.

So it will map onto itself at intervals of 72 degrees.
