A polygon with 20 sides is an icosagon.
It has 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
It has 20 vertices.

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.

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
It has 20 vertices.

20, because a polygon has the same number of sides and vertices.
