Shapes are an essential part of geometry, and every shape has its unique name. However, not everyone is familiar with every shape's name, and some shapes are quite uncommon. One such shape is a 9-sided shape. What is it called? Let's find out!

The Basics of Polygons

Before we dive into the answer, let's understand the basics of polygons. A polygon is a two-dimensional shape with straight lines and angles. Polygons can have any number of sides, and each side should connect two vertices (corners). Moreover, the interior angles of any polygon sum up to a particular value, depending on the number of sides.

Common Polygons

Some of the most common polygons are triangles, quadrilaterals, pentagons, hexagons, heptagons, and octagons. Triangles have three sides, quadrilaterals have four sides, pentagons have five sides, hexagons have six sides, heptagons have seven sides, and octagons have eight sides. These shapes are familiar to most people, and their names are easy to remember.

A 9-Sided Polygon

Now, let's talk about a 9-sided polygon. A 9-sided polygon is called a nonagon. The word nonagon comes from the Latin word "nonus," which means nine, and "gonon," which means angles. A nonagon has nine straight sides and nine vertices.

Nonagons are not very common in everyday life, but you might come across them in various fields, such as architecture, engineering, and design. For instance, the United States Enrichment Corporation headquarters in Maryland is a nonagon-shaped building, and it is an excellent example of the use of this shape in architecture.

Properties of a Nonagon

Now that we know what a nonagon is let's look at some of its properties. Like all polygons, a nonagon has specific properties that make it unique. Here are some of the essential properties of a nonagon:

A nonagon has nine sides and nine vertices.
The sum of the interior angles of a nonagon is 1260 degrees.
Each interior angle of a nonagon measures 140 degrees.
A nonagon can be regular or irregular.
In a regular nonagon, all sides and angles are equal.
An irregular nonagon has sides and angles of varying lengths and measures.

Conclusion

Now that we know what a 9-sided shape is called let's recap. A 9-sided polygon is called a nonagon. It has nine straight sides and nine vertices. Nonagons are not very common in everyday life, but they are used in various fields such as architecture, engineering, and design. Nonagons have specific properties that make them unique, and they can be regular or irregular.

So, the next time you come across a 9-sided shape, you know what it's called!
