Formula To Calculate Interior Angles Of A Polygon

The exterior angle of a regular n sided polygon is 360 n worksheet using the formula for the sum of exterior angles.

Formula to calculate interior angles of a polygon. So you would use the formula n 2 x 180 where n is the number of sides in the polygon. So to calculate the sum of. Interior angle of a polygon sum of interior angles number of sides.

Each triangle has 180. Polygons are also classified as convex and concave polygons based on whether the interior angles are pointing inwards or outwards. Sum of interior angles of a three sided polygon can be calculated using the formula as.

The sum of the measures of the interior angles of a polygon with n sides is n 2 180. To find the sum of the interior angles in polygons you first need to divide the polygon into triangles. Sum of interior angles p 2 180 60 40 x 83 3 2 180 183 x 180 x 180 183.

S n 2 180 this is the angle sum of interior angles of a polygon. Interior angle sum of the interior angles of a polygon n. All the interior angles in a regular polygon are equal.

Interior and exterior angle formulas. The sum of the interior angles is. The formula for finding the sum of the interior angles of a polygon is the same whether the polygon is regular or irregular.

In order to find the measure of a single interior angle of a regular polygon a polygon with sides of equal length and angles of equal measure with n sides we calculate the sum interior anglesor red n 2 cdot 180 and then divide that sum by the number of sides or red n. The measure of each interior angle of an equiangular n gon is if you count one exterior angle at each vertex the sum of the measures of the exterior angles of a polygon is always 360. Hence we can say now if a convex polygon has n sides then the sum of its interior angle is given by the following formula.
