I looked at the diagrams constructed of different polygons. The first diagram was constructed of 9 hexagons around a point. The angle around a point is equal to 360∘. Therefore, to find out the angle of rotation I divided by 9 to get 360∘÷9=40∘. So the angle of rotation is 40∘.

The second diagram was constructed of 8 pentagons around a point. So, as before, I divided 360 by 8 to get 360∘÷8=45∘. So the angle of rotation is 45∘.
