A Shape With 10 Sides Is Called:
Shapes come in all sizes and forms, from a simple circle to a complex dodecahedron. Each shape has its unique characteristics, and understanding them helps us learn more about the world around us. In this article, we will focus on one specific shape - the one with ten sides. Have you ever wondered what a shape with ten sides is called? Let's explore this interesting question together.
What is a Polygon?
Before delving deeper into the world of ten-sided shapes, let's first understand what a polygon is. In geometry, a polygon is a closed two-dimensional figure with straight sides. Polygons can have any number of sides, starting from three and going up to infinity. Examples of polygons include triangles, squares, pentagons, and so on.
What is a Decagon?
A decagon is a polygon with ten sides and ten angles. The word decagon comes from the Greek words "deka" meaning ten and "gonia" meaning angle. A decagon is a regular polygon, which means all its sides and angles are equal. In a regular decagon, each angle measures 144 degrees, and the sum of all angles is 1440 degrees.
Properties of a Decagon
A decagon has several unique properties that make it stand out from other polygons. Some of these properties include:
- A decagon has ten sides and ten angles.
- All sides of a regular decagon are equal in length.
- All angles of a regular decagon are equal in measure.
- The sum of all angles in a decagon is 1440 degrees.
- The exterior angles of a regular decagon measure 36 degrees each.
Real Life Examples of Decagons
Decagons may not be as common as squares or circles, but they can be found in various real-life objects and structures. For example, the United States Department of Defense has a building called The Pentagon, which is a five-story, five-sided building with a central courtyard. The outer shape of The Pentagon is a regular decagon. Additionally, the shape of some stop signs and traffic cones is a regular decagon.
How to Draw a Decagon
Drawing a decagon can be challenging, but with a few simple steps, anyone can do it. Here's how:
- Draw a straight line segment of any length and mark its endpoints.
- Using a protractor or compass, draw an angle of 36 degrees at one endpoint of the line segment.
- From the same endpoint, draw another 36-degree angle in the opposite direction.
- Repeat step 3 until you have drawn ten 36-degree angles.
- Connect the endpoints of each angle to form a regular decagon.
Conclusion
In conclusion, a shape with ten sides is called a decagon. Decagons are fascinating polygons with unique properties and can be found in various real-life objects and structures. They can be challenging to draw, but with some practice and patience, anyone can master the art of drawing a decagon. We hope you enjoyed this article and learned something new about the world of shapes.
Remember, shapes are everywhere, and understanding them helps us make sense of the world around us.
