What Does A Decagon Look Like?
Decagon is a geometrical shape that is made up of ten sides and ten vertices. It is a two-dimensional shape and belongs to the family of polygons. In this article, we will explore the characteristics of a decagon and how it looks like.
Characteristics of a Decagon
As mentioned earlier, a decagon has ten sides and ten vertices. All the sides of a decagon are of equal length, and all the internal angles of a decagon are of equal measure. The sum of all the internal angles of a decagon is 1440 degrees. A decagon can be regular or irregular.
Regular Decagon
A regular decagon is a decagon in which all the sides and angles are of equal measure. In a regular decagon, the internal angle measures 144 degrees, and the external angle measures 36 degrees. A regular decagon can be inscribed in a circle, and all the vertices of the decagon lie on the circumference of the circle.
Irregular Decagon
An irregular decagon is a decagon in which all the sides and angles are not of equal measure. In an irregular decagon, the internal angles have different measures, and the sides have different lengths. An irregular decagon cannot be inscribed in a circle, and its vertices do not lie on a single circumference.
How Does a Decagon Look Like?
A decagon has a distinct shape that is easy to recognize. It looks like a ten-sided polygon with ten vertices. The sides of a decagon are straight lines that connect the vertices, and the angles are the points where the sides meet.
The shape of a regular decagon is more symmetrical than an irregular decagon. In a regular decagon, all the sides and angles are of equal measure, and the shape is more uniform. On the other hand, an irregular decagon has sides and angles of different measures, and the shape is more random.
When you draw a decagon, you can use a ruler to make sure that all the sides are of equal length. You can also use a protractor to measure the angles and make sure that they are of equal measure.
Uses of a Decagon
Decagons are not only interesting shapes, but they also have practical uses. Decagons can be found in various applications, such as architecture, art, and design. For example, the Pentagon building in the US is a decagon-shaped building that houses the Department of Defense. Decagons can also be found in jewelry, logo designs, and other decorative items.
Conclusion
Decagons are fascinating geometrical shapes that have ten sides and ten vertices. They can be regular or irregular, and their internal angles and sides have different measures. A regular decagon is more symmetrical than an irregular decagon, and it is easier to recognize. Decagons have practical applications in various fields, such as architecture, art, and design. Understanding the characteristics and appearance of a decagon can be useful for anyone who wants to explore the world of geometry.
So, next time you come across a decagon, you will know what it looks like!
