It is: (13-2)*180 = 1980 degrees

A polygon with any number of sides can have an interior angle measuring 108 degrees.
If the interior angles of a polygon add up to 1980 degrees then it has 13 sides
(number of sides-2)*180 = total sum of interior angles
The smallest regular polygon, an equilateral triangle, has interior angles of 60. A square has interior angles of 90. There can't exist a regular polygon with interior angles of 30.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
The interior angles of a 40 sided polygon add up to 6840 degrees
If measured on the inside of the polygon, the it is an interior angle.
For any polygon of N sides, the sum of the interior angles (in degrees) is 180*N-360, which for N=20 is 3240°
Suppose the polygon has n sides Then sum of interior angles = (n-2)*180 degrees = 3960 degrees so n-2 = 3960/180 = 22 and so n = 24
If you mean interior angles of 2800 degrees then no such polygon exist because one of its sides woud not meet up with another side.
A polygon is a closed figure in the plane. It has an inside and an outside.The angles on the inside are the interior angles. An exterior angle is the angle between any side of the polygon and a line extended from the next side.Here is an example to help.If you draw an triangle, the angles inside it are interior angles. Then if you extend any side, the angle between that line and the next side is the exterior angle.The sum of the exteriors is always 360. For a polygon with n sides, the sum of the interior angles is 180 (n-2) degrees.
