5. How does the number of rotational symmetries compare to the number of sides a regular polygon has?

6. Point symmetry means a shape has 180 degree rotational symmetry.  Which of the previous shapes had rotational symmetry? 

7. Will a regular polygon with an even number of sides have point symmetry?  Will a regular polygon with an odd number of sides have point symmetry?  Explain. 

8. A full revolution is 360 degrees.  A triangle had 3 rotational symmetries.  360/3 = 120, which was the first angle measurement where the triangles overlapped.  Does this pattern work for the square and hexagon?  Show your work.

9. How many rotational symmetries would a 10 sided regular polygon have?

10. What would be the measurement in degrees for the first rotational angle measurement for the 10 sided regular polygon?
