Ten Sided Shape Is Called
Welcome to our blog where we will be discussing the ten-sided shape and what it is called in the world of geometry. Geometry is a branch of mathematics that deals with the study of shapes, sizes, and positions of objects. Shapes are the building blocks of geometry, and they come in different sizes and forms, each with its unique name. The ten-sided shape is one of the many shapes in geometry, and in this article, we will explore what it is called and some interesting facts about it.
The Ten-Sided Shape
The ten-sided shape is a polygon with ten sides and ten vertices. A polygon is a closed shape with straight sides. The ten-sided shape is also known as a decagon. The word "decagon" comes from the Greek words "deka," meaning ten, and "gonia," meaning angle. A decagon has ten angles, and each angle measures 144 degrees. The sum of the interior angles of a decagon is 1440 degrees.
The Properties of a Decagon
Like all polygons, the ten-sided shape has certain properties that make it unique. Some of the properties of a decagon include:
- It has ten sides and ten vertices.
- It has ten angles, each measuring 144 degrees.
- The sum of the interior angles is 1440 degrees.
- The exterior angles add up to 360 degrees.
- It can be divided into ten triangles.
- It has five diagonals.
Real-Life Examples of Decagons
Decagons are not commonly found in everyday life, but they can be seen in some objects and structures. Some examples of objects that have a decagonal shape include:
- Coins: The United States dime has a decagonal shape.
- Stadiums: Some stadiums, such as the Olympic Stadium in Munich, Germany, have a decagonal shape.
- Flowers: Some flowers, such as the dahlia, have a decagonal shape.
Other Types of Decagons
There are several types of decagons, each with its unique properties. Some of the types of decagons include:
Regular Decagon
A regular decagon is a decagon with all sides and angles equal. It is also called an equilateral decagon. In a regular decagon, each interior angle measures 144 degrees, and each exterior angle measures 36 degrees.
Irregular Decagon
An irregular decagon is a decagon with sides and angles of different lengths and sizes. It does not have equal sides or angles. An irregular decagon can be concave or convex.
Conclusion
In conclusion, the ten-sided shape is called a decagon. It is a polygon with ten sides, ten vertices, and ten angles. A decagon has several unique properties, including the sum of its interior angles, which is 1440 degrees. Decagons can be found in coins, stadiums, and flowers, among other objects. There are different types of decagons, including the regular decagon and the irregular decagon. Understanding the properties of decagons is essential in the study of geometry and mathematics.
