Question

20. What is the order of rotational symmetry for each design (i.e. what is the angle of rotation to create

Answer 1

Your answer should be:

The order of rotational symmetry of a regular polygon is the same as the number of sides of the polygon. You can also deduce the order of rotational symmetry by knowing the smallest angle you can rotate the shape through to look the same. 180° = order 2, 120° = order 3, 90° = order 4.

I hope this helped :)
