Homework help has a great explanation of the answer to this question (see reference for the link).
We use a formula to find the sum of the interior angles of any polygon. In this formula, the letter n stands for the number of sides, or angles, that the polygon has.
sum of angles = (n - 2)180°
So for a triangle (n = 3), The angles add to 180
For a square (n = 4), the angles add to 360
For a octagon (n = 8) the angles add to 1080

CoachIt depends on the polygon. The sum of the interior angles of a triangle is 180o. For every additional side, there are 180o more. The sum of the interior angles of a polygon can be found using this equation:
Sa=180(sn-2)
Where Sa=the sum of the interior angles, and
sn=the number of sides that the polygon has.
Sn has to be a whole number greater than 2.

Sum of angles in a polygon?
The sum of the exterior angles of any polygon is 360 degrees.
What is the sum of a 23 sided polygon's exterior angles?
The sum of the exterior angles of any polygon is 360 degrees
What is the sum of exterior angles in a 10 sided polygon?
The sum of the exterior angles of ANY polygon is 360 degrees.
What is the sum of the interior angles of a polygon with 25 sides?
The formula for the sum of the interior angles of a polygon is: 180 * (n - 2) where n is the number of sides of the polygon. So the sum of the angles of a polygon with 25 sides is 180 * 23 = 4,140.
The formula for finding the sum of the angles of a polygon?
The formula for finding the sum of all angles of a polygon is: N = number of sides (N-2)180 = The sum of all angles
