# Which angle rotational symmetry does the regular nonagon has? Check all that apply.

A nonagon is a nine-sided polygon. A regular nonagon has 9 sides and 9 angles of the same measure,

## Answer: The degree of rotation for a Nonagon is 40º.

See detailed answer.

**Explanation:**

The measure of central vertex angle = 360º / 9 = 40º

⇒ The degree of rotation for a 9 sided polygon = 40º

Also, the rotational symmetry about the center = 40º
