Question

Is there a 20 sided shape?

Answer 1

Hint: Here in this question based on polygon shapes, we have to discuss or explain the 20 sided shape. In 2D shape the polygon starts with 3 sides but it can go up to infinity sides, there is no limit of sides to construct a polygon hence the 20 sided polygon exists and it is named as ‘icosagon’ .

Complete step by step answer:
Polygons are 2-dimensional shapes that have a certain number of sides. They are made of straight lines, and the shape is "closed" ; simply all the lines or sides connect up.
Polygons start at only three sides but can go up to infinity. There is no limit to how many sides a polygon can have.
Consider the given question
Is there a 20 sided shape?
We can say easily ‘Yes’
Because there is a polygon with 20 sides. In geometry, a 20 sided shape, i.e. 2 -dimensional shape is called an icosagon.
In a 20-sided shape or icosagon, the sum of all the interior angles is equal to $${3240}^{\circ }$$ degrees.
An icosagon with all sides having equal measurement is called a regular icosagon.
The 20 sided shape or icosagon diagrammatically represented as:

Note:
Remember the polygon starts with minimum three sides up to the infinity sides and it always should be closed. Some polygons have very straightforward names for the first ten or twenty names like triangle, square, pentagon, hexagon etc. They use a basic prefix naming system. Di, tri, tetra, penta, hexa and so on.
