**Is there a shape with 20 sides?**

Yes, there is a polygon with 20 sides. In geometry, a 20 sided shape, i.e. 2d shape is called an icosagon. The sum of all the interior angles of an icosagon is 3240 degrees. An icosagon with all equal sides is called a regular icosagon.

**What’s a regular icosagon?**

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

**What is the meaning of icosagon?**

A polygon with twenty sides and twenty angles

icosagon (plural icosagons) (mathematics) A polygon with twenty sides and twenty angles.

## Why do shapes end in gon?

Gon definition Gon is defined as that a shape has a specific number of angles. An example of the gon suffix is a five-sided shape; a pentagon. A figure having a specified kind or number of angles.

## How to construct a regular icosagon?

As 20 = 22 × 5, regular icosagon is constructible using a compass and straightedge, or by an edge- bisection of a regular decagon, or a twice-bisected regular pentagon : In the construction with given side length the circular arc around C with radius CD, shares the segment E20F in ratio of the golden ratio.

**How do you find the perimeter of a regular icosagon?**

The regular icosagon is also called a regular isodecagon, because to obtain a regular icosagon, what you must do is bisect (divide into two equal parts) each side of a regular decagon (10-sided polygon). To calculate the perimeter “P” of a regular polygon, the number of sides is multiplied by the length of each side.

**Is the globe an irregular icosagon?**

The Globe, the outdoor theater used by William Shakespeare’s acting company, was discovered to have been built on an icosagonal foundation when a partial excavation was done in 1989. As a golygonal path, the swastika is considered to be an irregular icosagon. A regular square, pentagon, and icosagon can completely fill a plane vertex .

### Is the swastika an irregular icosagon?
