What Is Ten Sided Shape Called?
Geometry is a fascinating branch of mathematics that deals with shapes, sizes, and positions of objects. When you think of shapes, you probably think of the basic ones like squares, circles, triangles, and rectangles. However, there are many more shapes out there, including polygons. Polygons are shapes with straight sides, and they come in many different varieties. In this article, we will be discussing one of the less common polygons – the ten-sided shape.
What is a Ten-Sided Shape?
A ten-sided shape is a polygon with ten straight sides and ten angles. It is also known as a decagon. The word "decagon" comes from the Greek word "deka," which means ten. A decagon is a two-dimensional shape, which means it lies flat on a surface. The sides of a decagon can be of equal length or different lengths, depending on the type of decagon.
Types of Decagons
There are two types of decagons: regular decagons and irregular decagons. A regular decagon has sides of equal length and angles of equal measure. An irregular decagon has sides and angles of different measures. There are many different types of irregular decagons, depending on the lengths and angles of their sides.
Regular Decagons
A regular decagon is a symmetrical polygon with ten equal sides and ten equal angles. Each angle measures 144 degrees, and the sum of all the angles is 1440 degrees. The regular decagon is a fascinating shape because it has a lot of interesting properties. For example, if you draw lines from each vertex of a regular decagon to every other vertex, you will get a star shape with ten points.
Irregular Decagons
Irregular decagons are polygons with sides and angles of different measures. There are many different types of irregular decagons, depending on the lengths and angles of their sides. Some examples of irregular decagons include pentagon-star, concave decagons, and crossed decagons.
Properties of Ten-Sided Shapes
Like all polygons, ten-sided shapes have unique properties that make them different from other shapes. Here are some of the properties of ten-sided shapes:
- A ten-sided shape has ten angles.
- The sum of the angles in a ten-sided shape is 1440 degrees.
- A regular ten-sided shape has ten equal sides and ten equal angles.
- An irregular ten-sided shape has sides and angles of different measures.
- A ten-sided shape can be convex or concave.
Applications of Ten-Sided Shapes
Ten-sided shapes may not be as common as other polygons, but they still have many applications in the real world. Here are some examples:
- Ten-sided stop signs are used to control traffic on roads.
- Many sports balls, such as soccer balls and basketballs, are made up of ten-sided shapes.
- Some architectural designs incorporate ten-sided shapes.
- Ten-sided shapes are used in some types of art and design.
