Take the number of sides and subtract 2, then multiply that answer by 180.
(8-2) x 180 = 6 x 180 = 1080
Use this form to work out the problem: (n - 2)180° where n is the number of sides Suppose that we have a regular polygon. This is the example of a convex polygon. Given that we have a 5-sided convex polygon, we obtain: (5 - 2)180° = 3 * 180° = 540°
The sum of what of a 92 sided polygon? The lengths of the sides? The exterior angles? The interior angles?
The interior angles of a 23 sided polygon add up to 3780 degrees
The sum of the interior angles of a polygon with n sides is 180o × (n - 2), consequently the sum of the interior angles of a 28-sided polygon is 4680o (180o × 26).

The interior angles of a 14 sided polygon add up to 2160 degrees
A convex hexagon is a simple polygon whose interior is a convex set. It is a six-sided polygon, and it has no angles pointing inwards, meaning that no internal angles can be more than 180 degrees.
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.
The sum of all the interior angles is 720 degrees.
The sum of the interior angles of a convex polygon with n sides is given by (n-2)x180o. So for a 40 sided polygon n=40; thus (40-2)x180o = 38x180o = 6840o.
The sum of the interior angles of a triangle is 180 deg. For a convex polygon with n sides we can divide it to n-2 triangles. So the answer, if the polygon is convex, is (13-2)*180= 1980 deg * * * * * The polygon need not be convex. The formula for the sum of the interior angles is valid as long as the polygon is simple - that it, its sides do not cross each other inside the polygon.
The sum of the interior angles of any n-sided polygon is always (n - 2) x 180.Therefore, the sum of the angles of a 23-sided polygon is (23 - 2) x 180 = 3780.
The interior angles of an 11 sided polygon add up to 1620 degrees
Use this form to work out the problem: (n - 2)180° where n is the number of sides Suppose that we have a regular polygon. This is the example of a convex polygon. Given that we have a 5-sided convex polygon, we obtain: (5 - 2)180° = 3 * 180° = 540°
The sum of the interior angles of a four-sided polygon is 360 degrees.
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
The interior angles of a 17 sided polygon add up to 2700 degrees
