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 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?
