What Is A Shape Called With 11 Sides?
Have you ever wondered what a shape with 11 sides is called? Well, wonder no more! In this article, we will explore the world of shapes and discover the name of the elusive 11-sided shape.
What is a Polygon?
Before we dive into the world of 11-sided shapes, let's first define what a polygon is. A polygon is a two-dimensional shape with straight sides. The sides of a polygon must connect to form a closed shape. Triangles, squares, and rectangles are all examples of polygons.
What is an 11-Sided Polygon Called?
An 11-sided polygon is called a hendecagon. The name hendecagon comes from the Greek words "hendeka" meaning eleven and "gonia" meaning angle.
Properties of a Hendecagon
Like all polygons, a hendecagon has certain properties. One property is that the sum of the interior angles of a hendecagon is equal to 1620 degrees. Another property is that a hendecagon has 55 diagonals, which are line segments that connect two non-adjacent vertices.
Regular and Irregular Hendecagons
A hendecagon can be either regular or irregular. A regular hendecagon has all sides and angles equal in measure, while an irregular hendecagon has sides and angles of different measures.
Real-Life Examples of Hendecagons
While you may not encounter hendecagons in your everyday life, they can be found in various places. For example, the shape of some soccer balls can be modeled as a hendecagon. Additionally, some buildings and monuments may feature hendecagon-inspired designs.
Other 11-Sided Shapes
While a hendecagon is the only 11-sided polygon, there are other 11-sided shapes that exist. For example, a Reuleaux polygon is a curve of constant width that is formed from the intersection of three or more circles of equal radius. The Reuleaux polygon with 11 sides is called an hendecagram.
In Conclusion
Now that you know what an 11-sided shape is called, you can impress your friends with your knowledge of geometry. The hendecagon may be a rare shape, but it has its place in the world of mathematics and design. So, the next time you come across an 11-sided shape, you'll know exactly what to call it - a hendecagon!
Remember, learning about shapes and geometry can be fun and fascinating. Keep exploring and discovering new things!
