Are you wondering what a polygon with nine sides is called? You've come to the right place! In this article, we will explore the world of polygons and discover the name of this unique shape. So, let's dive in!

What is a Polygon?

A polygon is a two-dimensional shape with straight sides that are connected to form a closed figure. Polygons can have any number of sides, from three to infinity. The most common polygons are triangles, rectangles, and squares. However, polygons with more sides can get a little tricky when it comes to naming them.

What is a 9-Sided Polygon Called?

A 9-sided polygon is called a nonagon. The word "nonagon" comes from the Latin words "nonus," which means "ninth," and "gonon," which means "angle." Therefore, a nonagon is a nine-angled polygon.

How to Draw a Nonagon?

To draw a nonagon, follow these steps:

Draw a straight line segment of any length and mark its midpoint.

With the midpoint as the center, draw a circle with the same length as the line segment.

Divide the circle into nine equal parts using a protractor or compass.

Connect the points on the circle with straight lines to form a nonagon.

Some Facts About Nonagons

Here are some interesting facts about nonagons:

A nonagon has nine sides, nine angles, and 27 diagonals.

A regular nonagon has nine equal sides and nine equal angles.

A nonagon has an interior angle sum of 1260 degrees.

The area of a nonagon can be calculated using the formula: Area = (9/4) × s² × cot(π/9), where s is the length of one side.

What are Some Real-Life Examples of Nonagons?

Nonagons are not common shapes in everyday life. However, you can find them in various objects and structures, such as:

The shape of the Fruit of Life, which is a sacred geometrical pattern made up of multiple nonagons.

The design of some stop signs, which are octagons with an additional triangle on each side.

The layout of the Enneagram, a nine-pointed diagram used for personal development and spiritual growth.

Conclusion

So, there you have it! A polygon with nine sides is called a nonagon. We have also learned how to draw a nonagon, some interesting facts about this shape and where we can find it in real life. Knowing the names of polygons can be helpful in various fields, such as architecture, geometry, and mathematics. We hope this article has been informative and enjoyable for you.
