In geometry, a nonagon (/ ˈ n ɒ n ə ɡ ɒ n /) or enneagon (/ ˈ ɛ n i ə ɡ ɒ n /) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, "ninth" + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

A nonagon, also known as an enneagon or a 9-gon is a shape with 9 sides and 9 corners. All sides of a regular nonagon are the same length. Each corner is 140°. All corners added together equal 1260°. The amount of space a regular nonagon takes up is. a …

A nonagon is a polygon that has nine sides. It is also referred to as an enneagon or 9-gon. There are various types of nonagons; the figure below depicts a few. A regular nonagon has angles and interior angles that are all equal. Below are some properties of a regular nonagon, as well as some properties that apply to all nonagons.
