The Name Of The 10 Sided Polygon: Explained
Geometry can be an intimidating subject for many people, but understanding the basics can help you appreciate the beauty and complexity of shapes and figures. One of the most interesting shapes in geometry is the 10 sided polygon, also known as a decagon. In this article, we'll explore the name of this unique shape and its properties in relaxed English language.
What is a Decagon?
A decagon is a polygon with 10 sides, 10 angles and 10 vertices. It is a regular polygon, meaning all of its sides and angles are equal. A decagon is a two-dimensional shape, which means it has length and width, but no height.
The Name of a Decagon
The name of the decagon comes from two Greek words – "deka," meaning ten, and "gonia," meaning angle. So, the name literally means "ten angles."
Another way to name a decagon is by using the number of sides it has. For example, a 10 sided polygon can be called a "10-gon."
Properties of a Decagon
As mentioned earlier, a decagon is a regular polygon, which means all of its sides and angles are equal. Here are some other interesting properties of a decagon:
- Each interior angle measures 144 degrees
- The sum of all interior angles is 1440 degrees
- The sum of all exterior angles is 360 degrees
- The ratio of the length of the diagonal to the length of the side is approximately 1.61803398875, which is known as the golden ratio
Examples of Decagons in Real Life
You may not realize it, but decagons can be found in many objects and structures around us. Here are a few examples:
- A stop sign is a regular decagon
- The United States Coast Guard uses a decagon-shaped logo
- The Washington Monument in Washington D.C. has a decagon-shaped base
How to Calculate the Area of a Decagon
Calculating the area of a decagon can be a bit tricky, but it is possible with the right formula. Here's how you can do it:
- Divide the decagon into 10 congruent triangles
- Calculate the area of one of the triangles using the formula: Area = 1/2(base x height)
- Multiply the area of one triangle by 10 to get the total area of the decagon
Conclusion
In conclusion, a decagon is a fascinating shape with many interesting properties. Its name comes from the Greek words for "ten angles," and it is a regular polygon with 10 sides, angles and vertices. We hope this article has helped you understand more about the name of the 10 sided polygon and its properties.
Whether you're a student studying geometry or just someone who appreciates the beauty of shapes and figures, the decagon is definitely a shape worth exploring further. So, go ahead and see if you can find any more examples of decagons in the world around you!
Remember, learning is a lifelong process, and geometry is just one of the many subjects that can enrich your understanding of the world.
