What Is A 10 Sided Polygon Called?
Geometry is a fascinating field of mathematics that deals with the study of shapes, sizes, and positions of objects. One of the most interesting shapes that you can encounter is a polygon. A polygon is a closed shape that has straight sides, and it can have any number of sides. In this article, we will be focusing on a specific type of polygon - one that has ten sides. What is a ten-sided polygon called? Let's find out!
Defining Polygons
Before we dive into the ten-sided polygon, let's define what a polygon is. A polygon is a two-dimensional shape that is made up of straight lines. The lines that make up a polygon are called sides, and the points where the sides meet are called vertices. Polygons can have any number of sides, and they can be classified based on the number of sides they have. For example, a polygon with three sides is called a triangle, and a polygon with four sides is called a quadrilateral.
The Ten-Sided Polygon
A ten-sided polygon is a polygon that has ten sides. Simple, right? But what is it called? The name of a polygon depends on the number of sides it has. A ten-sided polygon is called a decagon. The word 'decagon' comes from the Greek word 'deka' which means ten, and 'gonia' which means angle.
Types of Decagons
Decagons can be classified based on their properties. There are two types of decagons - regular and irregular. A regular decagon is a decagon in which all the sides and angles are congruent. An irregular decagon is a decagon in which the sides and angles are not congruent.
Regular Decagons
A regular decagon has ten sides of equal length and ten angles that are also equal. The angles of a regular decagon measure 144 degrees each. The regular decagon has many interesting properties. For example, it can be used to construct a pentagon, which is a polygon with five sides, using only a compass and a straightedge.
Irregular Decagons
An irregular decagon is a decagon in which the sides and angles are not congruent. An irregular decagon can have sides of different lengths and angles of different measures. There are many different types of irregular decagons, each with its own unique properties.
Uses of Decagons
Decagons are used in many different fields, including architecture, engineering, and mathematics. In architecture, decagons are used to create interesting and unique shapes for buildings. In engineering, decagons are used in the design of gears and other mechanical components. In mathematics, decagons are used to teach concepts such as symmetry and angles.
Conclusion
In conclusion, a ten-sided polygon is called a decagon. Decagons can be classified as regular or irregular, depending on their properties. Regular decagons have ten sides of equal length and ten angles that are also equal. Irregular decagons can have sides of different lengths and angles of different measures. Decagons are used in many different fields, including architecture, engineering, and mathematics.
So, there you have it - everything you need to know about what a ten-sided polygon is called. We hope you found this article informative and interesting!
