What is the sum of the exterior angles of a 21 sided polygon?
The sum of the exterior angles of any polygon, regardless of the number of sides, is always 360 degrees. Therefore, the sum of the exterior angles of a 21-sided polygon is 360 degrees.
What is a 21 sided polygon called?
Oh, dude, a 21-sided polygon is called a icosikaihenagon. Yeah, I know, it sounds like something you'd make up after a few too many drinks at a math convention. But hey, that's the beauty of geometry - it's like a party where all the shapes get together and have a good time.

What is the size of each angle of a regular polygon with 23 sides?
The sum of the angles of a polygon is equal to 180° times (n-2) where n is the number of sides.For a 23-sided polygon, that would give a total of (180°) x (21) = 3780°. If the angles are all the same, each would be 3780° ÷ 23 = 164.3478°
