What Do You Call A Shape With 10 Sides?
Shapes are all around us, from the circles on our coffee cups to the squares on our computer screens. But have you ever wondered what you call a shape with 10 sides? In this article, we'll explore the answer to that question and more in relaxed English.
What is a Shape with 10 Sides Called?
A shape with 10 sides is called a decagon. The word "decagon" comes from the Greek words "deka," meaning ten, and "gonia," meaning angles. A decagon has ten angles and ten sides of equal length, making it a regular polygon.
What are the Properties of a Decagon?
As mentioned earlier, a decagon has 10 sides of equal length and 10 angles of equal measure. The sum of the interior angles of a decagon is 1440 degrees, and each angle measures 144 degrees. The exterior angles of a decagon, on the other hand, add up to 360 degrees, and each exterior angle measures 36 degrees.
Another interesting property of a decagon is that it can be divided into 7 triangles. These triangles share a common center, and their vertices lie on the decagon's vertices. This property makes the decagon useful in various applications, such as in architecture and design.
Examples of Decagons in Everyday Life
Although decagons are not as common as other shapes, they can still be found in everyday life. Some examples of decagons include:
- The shape of a home plate in baseball
- The shape of a stop sign
- The shape of a soccer ball
These objects are essential in our daily lives, and it's interesting to note that they all share the same shape - a decagon.
How to Draw a Decagon
Drawing a decagon is relatively easy, and you don't need any special tools to do it. Here's how:
- Draw a straight line and mark the midpoint
- From the midpoint, draw a perpendicular line of equal length on both sides
- Connect the endpoints of the perpendicular line to form a triangle
- Repeat the process on each vertex of the triangle until you have a decagon
Alternatively, you can use a compass and a straightedge to draw a decagon more accurately.
Why is Knowing About Decagons Important?
Knowing about decagons may not seem essential, but it can be useful in various fields. For example, architects and engineers use decagons to design buildings and structures. Mathematicians use decagons to study geometry and other mathematical concepts.
Additionally, learning about decagons can help improve your problem-solving skills and critical thinking. It can also expand your knowledge of shapes and geometry, which are essential in many aspects of life.
Conclusion
In conclusion, a shape with 10 sides is called a decagon. Decagons have ten sides of equal length and ten angles of equal measure, making them a regular polygon. They are used in various fields, such as architecture, mathematics, and design. Knowing about decagons can expand your knowledge of shapes and improve your problem-solving skills, making it a beneficial concept to learn.
So, next time you see a stop sign or a soccer ball, you'll know that it's a decagon!
