If it's a regular polygon, it's making a good stab at being a circle!
A polygon with 20 sides is an icosagon.
The name of a polygon with 20 or more sides is called "n-gon".
It has 360/20 = 18 sides
A 20-sided polygon is called an icosagon. In geometry, a polygon with n sides has n vertices. Therefore, a 20-sided polygon would have 20 vertices. Each vertex represents a point where two sides of the polygon intersect.

There is no such figure as a 20 degrees polygon.
There is a corresponding side to every angle. 20... A polygon has as many sides as it does angles.
A 20-sided polygon is called an icosagon. In geometry, a polygon with n sides has n vertices. Therefore, a 20-sided polygon would have 20 vertices. Each vertex represents a point where two sides of the polygon intersect.
A polygon with 5 or more sides can be a stop sign it has 8 sides.

There is no such polygon but if you meant exterior angles of 20 degrees then it will have 360/20 = 18 sides
A polygon with n sides had n*(n-3)/2 diagonals. So a 20 sided polygon would have 20*17/3 = 170
