Some 20-gons will have only one: 360 degrees.
Some 20-gons will have 2 (180 deg), some will have 90 deg, 72 deg, 36 deg of 18 deg. It depends on the extent of irregularity of the polygon.

Interior angles: 3240 degrees Exterior angles: 360 degrees
icosagon (20-gon? brush up on ur polygonal terms) anyway 162 degrees
3240 total degrees. Each angle is 162 degrees
Well, honey, an exterior angle of a polygon can be found by dividing 360 degrees by the number of sides. So for a 20-gon, each exterior angle would be 18 degrees. It's as simple as that, darling.
The sum of interior angle ( Sum-of-interior-angles-n-gon) of n-gon is:If we have a ,Then
