What is a Nonagon?

[IRORafael8]

I came across the term “nonagon” and want to understand its properties and real-life examples. Can someone explain?

 

[Robert Willian]

A nonagon is defined as a polygon with nine sides, nine angles and is a flat figure having two dimensions. A nonagon can take the form of a regular one (i.e. all sides and angles are equal) or an irregular one, and the total of the interior angles of all nonagons is always 1260 degrees.

A nonagon is a nine-sided polygon with nine angles.
For example, stop signs in some designs or geometric patterns in architecture may feature nonagonal shapes.

A nonagon is a nine-sided polygon in geometry. It has nine angles and nine straight sides. If all sides and angles are equal, it’s called a regular nonagon; otherwise, it’s irregular. Nonagons are less common than shapes like triangles or squares.

 

[Luca]

The nonagon is a nine-sided polygon with nine angles. When all the sides and angles are equal, it's called a regular nonagon; otherwise, it's known as an irregular nonagon.

A nonagon is just a shape with nine sides and nine corners. Think of it like a stop sign, but with nine edges instead of eight.

 

[jarwish]

A nonagon is a polygon with nine sides and nine angles. It can be regular, with all sides and angles equal, or irregular with varying lengths and angles.

 

[royjasika]

A polygon having nine angles and sides is known as a nonagon. When it is regular, then all sides and angles are equal, and the interior angles are 140 degrees each. Nonagons may be both regular and irregular and are researched in geometry and mathematics.

A nonagon is a polygon with nine sides and nine angles.

 

[Clara]

A nonagon is a polygon with nine sides, nine angles, and nine vertices.

 

[Cayson]

A nonagon is a polygon with nine sides and nine angles. It can be regular, with all sides and angles equal, or irregular, with sides and angles of different lengths and measures.

 

[Charles]

A nonagon is a polygon with nine sides and nine angles.

 

[Luca]

A nonagon is a nine-sided polygon with nine angles. If all sides and angles are equal, it is a regular nonagon, with each interior angle measuring 140°.

 

[Jacks will]

An enneagon or a nonagon is a polygon, which has a total of nine sides, as well as angles. Each and every side of a normal nonagon has a length of the same amount and the thereof angles amount to 140 degrees. Angles of any of the nonogons have a total sum of 1260 degrees. Architecture, some coins, and complicated geometric patterns will have nonagonal shapes.

 

[Michael Anderson]

An enneagon also known as a nonagon is a geometric polygon with a nine straight sides and nine interior angles. With a nonagon, there is no preferred side of it, and all the interior angles of the nonagons are equal to 140 degrees. It is known that the sum of all the interior angles of any polygon 9-gons results in 1260 degrees. The shapes can be seen in different areas, such as complex geometry, architecture and design patterns.
