The Fascinating World Of Nonagons: The Name Of Polygon With 9 Sides
As we delve deeper into the world of geometry, we come across several intriguing shapes that leave us in awe. One such shape is a nonagon, a polygon with nine sides. In this article, we will explore everything there is to know about nonagons, including their properties, types, and the name of polygon with 9 sides.
Properties of Nonagons
Nonagons are fascinating shapes that have some unique properties. Here are a few:
- Nonagons have nine sides, nine angles, and nine vertices.
- The sum of the interior angles of a nonagon is 1260 degrees.
- Nonagons can be either regular or irregular.
- Regular nonagons have sides of equal length and angles of equal measure.
- Irregular nonagons have sides and angles that are not equal in measure.
Types of Nonagons
Nonagons can be classified based on their properties and characteristics. Here are a few types of nonagons:
Regular Nonagons
Regular nonagons are nonagons that have sides of equal length and angles of equal measure. They are symmetrical and have nine lines of symmetry. A regular nonagon can be inscribed in a circle, with each vertex touching the circumference of the circle.
Irregular Nonagons
Irregular nonagons are nonagons that have sides and angles that are not equal in measure. They are asymmetrical and do not have any lines of symmetry. Irregular nonagons can be further classified into concave and convex nonagons.
Concave Nonagons
A concave nonagon is an irregular nonagon that has at least one angle greater than 180 degrees. It has at least one interior angle that "caves in" towards the center of the shape.
Convex Nonagons
A convex nonagon is an irregular nonagon that has all its angles less than 180 degrees. It does not have any interior angles that "cave in" towards the center of the shape.
The Name of Polygon with 9 Sides
Nonagon is the commonly used name of polygon with 9 sides. However, it is also known as enneagon, which is derived from the Greek word "ennea" meaning nine and "gonia" meaning angle. Nonagon is derived from the Latin word "nonus" meaning nine and "gonia" meaning angle. Both these names are correct and widely used in geometry.
Conclusion
Nonagons are fascinating shapes that have unique properties and characteristics. They can be regular or irregular, concave or convex. Nonagon is the commonly used name of polygon with 9 sides, but it is also known as enneagon. Whether you are a geometry enthusiast or just curious about shapes, nonagons are sure to leave you intrigued and awestruck.
So go ahead and explore the fascinating world of nonagons!
