Formula For Interior Angles Of Polygon
Sum of interior angles p 2 180 60 40 x 83 3 2 180 183 x 180.
Formula for interior angles of polygon. 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. If n is the number of sides of a polygon then the formula is given below. All the interior angles in a regular polygon are equal.
The interior angles of a polygon are those angles at each vertex that are on the inside of the polygon. Interior angles of a polygon formula. The sum of interior angles of a 3 sided polygon i e.
If n represents the number of sides then sum of interior angles of a polygon n 2 180 0 example. Let us discuss the three different formulas in detail. There is one per vertex.
Triangle is n 2 180 0 3 2 180 0 180 0. Sum of interior angles of a three sided polygon can be calculated using the formula as. For a regular polygon by definition all the interior angles are the same.
The sum of the measures of the interior angles of a polygon with n sides is n 2 180. Interior angles of a regular polygon 180 n 360 n. Interior and exterior angle formulas.
The formula can be obtained in three ways. S n 2 180 this is the angle sum of interior angles of a polygon. 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.
