A nonagon has how many sides?

The correct answer is: 9

A nonagon is a polygon that is characterized by having nine sides. The term "nonagon" comes from the Latin prefix "nonus," meaning nine, combined with the Greek word "gonia," which means angle. Therefore, it is a straightforward identification based on the definition of polygons. Each side of a nonagon connects at vertices, resulting in a total of nine distinct angles as well. This makes the answer, which indicates nine sides, the correct choice.
