Decagon is a ten-sided polygon that has been a topic of interest for mathematicians for years. In this article, we will discuss everything you need to know about the sides on a decagon. Whether you are a student or a professional, this guide will provide you with valuable information about decagons.

What is a Decagon?

A decagon is a polygon with ten sides and ten angles. It is a two-dimensional shape that has ten straight sides connecting ten vertices. The word 'decagon' comes from the Greek words 'deka' meaning ten and 'gonia' meaning angle.

How to Calculate the Length of the Sides on a Decagon?

The formula to calculate the length of the sides on a regular decagon is:

S = (2 * A * tan(π/10))

Where S is the length of the side, and A is the apothem. The apothem is the distance from the center of the decagon to the midpoint of the side.

Example:

Suppose we have a regular decagon with an apothem of 4 cm. We can calculate the length of the side as:

S = (2 * 4 * tan(π/10))

S = 8.0902 cm

Properties of Sides on a Decagon

Here are some essential properties of sides on a decagon:

Decagon has ten sides of equal length in the case of a regular decagon.

The sum of the length of all sides in a decagon is equal to the perimeter of the decagon.

The length of each side in a decagon is equal to the perimeter divided by ten.

The length of each side in a regular decagon can be calculated using the formula mentioned above.

Real-World Applications of Decagons

Decagons have several real-world applications. For example:

Decagonal nuts and bolts are used in various industries because of their strength and stability.

Decagonal tables and chairs are popular in the furniture industry because of their unique shape and design.

Decagonal buildings are aesthetically pleasing and are used in architecture and design.

Interesting Facts about Decagons

Here are some interesting facts about decagons:

Decagons are one of the few polygons that cannot be constructed using a compass and straightedge.

A decagon can be divided into seven triangles, five quadrilaterals, or two pentagons.

The interior angle of a decagon is 144 degrees, and the exterior angle is 36 degrees.

Conclusion

In conclusion, a decagon is a polygon with ten sides and ten angles. The length of the sides on a decagon can be calculated using a simple formula. Decagons have several real-world applications and interesting properties that make them unique. Whether you are a student or a professional, understanding decagons is essential in the field of mathematics and design.

So, if you are interested in learning more about decagons, this guide is an excellent starting point for you.

Happy learning!
