Shape Has 10 Sides: Everything You Need To Know
Shapes are one of the most basic concepts that we learn in our early years. We all know that a circle is round, a square has four sides, and a triangle has three. However, have you ever heard of a shape that has 10 sides? In this article, we'll explore everything you need to know about this unique shape.
What is a Shape with 10 Sides?
A shape with 10 sides is known as a decagon. The word "decagon" comes from the Greek words "deka" meaning ten and "gonia" meaning angle. A decagon is a two-dimensional shape that has ten straight sides and ten angles. Each angle in a decagon measures 144 degrees, and the sum of all the angles in a decagon is 1,440 degrees.
Types of Decagons
There are two types of decagons: regular and irregular. A regular decagon is a shape where all sides and angles are equal. An irregular decagon is a shape where all sides and angles are not equal. Regular decagons are symmetrical and have rotational symmetry of order 10, which means they can be rotated by 36 degrees and still look the same.
Regular Decagon
A regular decagon can be inscribed in a circle with each vertex touching the circle. The radius of the circle is equal to the distance between the center of the circle and one of the vertices of the decagon. The area of a regular decagon can be calculated using the formula:
Where s is the length of one side of the decagon.
Irregular Decagon
An irregular decagon can have sides and angles of any length and measure. There are no specific formulas to calculate the area or perimeter of an irregular decagon because each shape is unique.
Where Can You Find a Decagon?
Decagons are not commonly found in everyday life. However, you can find decagons in architecture, such as in the design of buildings and bridges. For example, the main building of the United States Department of Defense, known as The Pentagon, is a regular pentagon with five sides.
Fun Facts About Decagons
Conclusion
In conclusion, a decagon is a unique shape with 10 sides and 10 angles. It can be regular or irregular and has various interesting properties. Although it may not be a common shape, it is worth learning about and exploring for its unique characteristics.
So, the next time you come across a decagon, you'll know exactly what it is and why it's so special.
