What Do You Call A Shape With 11 Sides?
Shapes are one of the most basic concepts in geometry. From simple circles to complex polygons, shapes are ubiquitous in our daily lives. However, not all shapes are created equal. Some are more common and well-known than others. In this article, we will explore the topic of shapes with 11 sides and answer the question: What do you call a shape with 11 sides?
The Basics of Polygons
Before we dive into the specifics of 11-sided shapes, let's first review some basics about polygons. A polygon is a two-dimensional shape that is bounded by a finite number of straight line segments. Each segment is called a side, and each endpoint where two sides meet is called a vertex. Polygons can have any number of sides, but they must have at least three sides to be considered a polygon.
What is an 11-Sided Polygon?
An 11-sided polygon is a type of polygon that has 11 sides. It is also called an undecagon or hendecagon. The word "undecagon" comes from the Greek words "undeca," which means eleven, and "gon," which means angle. Similarly, the word "hendecagon" comes from the Latin words "hendeca," which also means eleven, and "gon," which means corner or angle.
The Properties of an 11-Sided Polygon
Like any other polygon, an 11-sided polygon has certain properties that distinguish it from other shapes. Here are some of the key properties of an 11-sided polygon:
- It has 11 sides, 11 vertices, and 11 angles
- The sum of its interior angles is equal to 1,620 degrees
- It can be either convex or concave
- It can be regular or irregular
Examples of 11-Sided Polygons
Although an 11-sided polygon may seem like a rare and obscure shape, it actually appears in many different contexts in our daily lives. Here are some examples of 11-sided polygons:
- Pentadecathlon, an athletic event in which participants compete in 15 track and field events
- The hendecagonal dihedral group, a group of symmetries of an 11-sided polygon
- The United Nations flag, which features an 11-sided polygon in the center
- The regular hendecagon, which can be constructed using a compass and straightedge
How to Calculate the Interior Angles of an 11-Sided Polygon
One of the most important properties of an 11-sided polygon is the sum of its interior angles. To calculate this sum, you can use the formula:
Sum of interior angles = (n - 2) x 180 degrees
Where n is the number of sides of the polygon. In the case of an 11-sided polygon, n = 11. Therefore, the sum of its interior angles can be calculated as:
Sum of interior angles = (11 - 2) x 180 degrees = 1,620 degrees
Conclusion
In conclusion, an 11-sided polygon is a type of polygon that has 11 sides. It is also known as an undecagon or hendecagon. Although it may seem like a rare and obscure shape, it appears in many different contexts in our daily lives. Whether you are interested in geometry, athletics, or flag design, understanding the properties of an 11-sided polygon can be a fascinating and rewarding pursuit.
