What shape has 9 sides and 9 angles?
nonagon
A nonagon is also called enneagon, which is derived from a Greek word called enneagonon, which means nine corners. The first use of the word nonagon dates back to the early 17th century, and has a Latin prefix (nona) and a Greek suffix (gon), making it a polygon with nine sides and nine angles.

How are the vertices of a 9-sided nonagon chosen?
Three of the 9 vertices are selected at random, and the tri (a) A regular nonagon (9-sided polygon) is inscribed in a circle as shown below. Three of the 9 vertices are selected at random, and the tri (a) A regular nonagon (9-sided polygon) is inscribed in a circle as shown below.
What do you call a shape with nine sides?
A nonagon is a closed shape that has nine sides. If it is a regular nonagon, all nine sides are the same length, and all the angles are equal. The sum of the interior angles of a nonagon is 1260 degrees. If it is a regular nonagon, then all nine angles have the same measurement of 140 degrees.
