A 5 Sided Shape Is Called
Geometry can be a fascinating subject, but sometimes the terminology can be confusing. If you're wondering what a 5 sided shape is called, you've come to the right place. In this article, we'll explore the various names for this shape, its properties and some of the real-world examples where it can be found.
What is a 5 Sided Shape?
A 5 sided shape is called a pentagon. The word "pentagon" comes from the Greek words "pente" meaning "five" and "gonia" meaning "angle". Therefore, a pentagon is a five-sided polygon with five angles.
Properties of a Pentagon
A pentagon has several properties that distinguish it from other polygons. One of the most notable is that all of its sides are of equal length, making it an example of a regular polygon. Additionally, each interior angle of a regular pentagon measures 108 degrees, while each exterior angle measures 72 degrees.
Another property of a pentagon is that it has five diagonals, which are line segments that connect non-adjacent vertices. A pentagon's diagonals can be used to divide the shape into five triangles, which can be useful when calculating its area or perimeter.
Real-World Examples of Pentagons
Pentagons can be found in a variety of real-world objects, from buildings to soccer balls. One example of a building that features pentagons is the United States Pentagon, which is the headquarters of the Department of Defense. This building is in the shape of a regular pentagon, with each of its sides measuring 921 feet long.
Another real-world example of a pentagon is a soccer ball. The ball is made up of 12 pentagons and 20 hexagons arranged in a spherical shape. The pentagons form the tops and bottoms of the ball, while the hexagons make up the sides.
Conclusion
In conclusion, a 5 sided shape is called a pentagon. It has several distinctive properties, including equal sides, interior angles measuring 108 degrees and five diagonals. Pentagons can be found in a variety of real-world objects, from buildings to soccer balls.
Understanding the properties and names of different shapes can be beneficial in various fields, including architecture, engineering, and mathematics. By knowing what a pentagon is, you can better understand the shapes and structures around you.
So, the next time you come across a five-sided shape, you'll know exactly what to call it!
