Nonagon has how many sides

In geometry, we may come across different types of polygons as shown in the figure given below. All of these polygons have different properties based on the number of sides and angles they have. A nonagon is a nine sided polygon and it is also called an Enneagon or 9-gon.

A nonagon has 9 vertices, 9 sides, and 9 interior angles. A polygon is a two-dimensional shape that is closed and has a finite number of sides. The sides of a polygon are made of straight line segments. For any polygon, the number of sides equals the number of interior angles. A polygon is named after the number of sides. For example, a polygon with three sides is called a triangle , a polygon with 4 sides is called a quadrilateral , a polygon with 5 sides is called a pentagon , etc.

Nonagon has how many sides

A regular nonagon is a 9-sided shape where every side is the same length and every corner has the same angle. All regular nonagons have the same shape, like this:. An irregular nonagon is a 9 sides shape where not every side and angle are equal. There are many different irregular nonagon shapes, here is an example:. The name nonagon is a combination of the words nonus Latin meaning ninth and gonon Latin meaning angle or corner. This is slightly unusual because most polygons use greek numbers in their name. An alternative name for a nonagon is enneagon , based on the Greek word ennea meaning nine. This name isn't used very often. The interior angles of a nonagon are shown here:. Where n is the number of sides.

There are various types of nonagons; the figure below depicts a few. Below is an example of an irregular nonagon:. Below are some properties of a regular nonagon, as well as some properties that apply to all nonagons.

Nonagon is a polygon that has 9 sides, 9 interior angles and 9 exterior angles. A nonagon shape can be regular or irregular depending upon the sides and angles. Let us learn more about the nonagon shape. A nonagon is a nine-sided geometrical figure which can be regular, irregular, convex or concave depending upon its sides and interior angles. Observe the figure given below to see what a nonagon looks like. As seen in the figure given above, a nonagon has 9 sides and the name 'Nonagon' was derived from the Latin words 'nonus' and 'gon' which mean a polygon with nine sides.

The area of a regular nonagon of side length a is given by. It can be also constructed using neusis , or by allowing the use of an angle trisector. The regular enneagon has Dih 9 symmetry , order There are 2 subgroup dihedral symmetries: Dih 3 and Dih 1 , and 3 cyclic group symmetries: Z 9 , Z 3 , and Z 1. These 6 symmetries can be seen in 6 distinct symmetries on the enneagon. John Conway labels these by a letter and group order. The dihedral symmetries are divided depending on whether they pass through vertices d for diagonal or edges p for perpendiculars , and i when reflection lines path through both edges and vertices.
