The general rule for finding the sum of interior angles in a regular polygon is (n – 2) × 180 °. This formula can be used to find the measure of a single interior angle of a regular polygon with n sides. To find the sum of interior angles, multiply the number of triangles formed inside the polygon by 180 degrees.
In this lesson, we will discuss how to find the measures of the interior angles of polygons and name polygons based on the number of sides. A regular polygon is a flat shape with all equal sides and angles. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle, divide the formula by the number of sides n: (n – 2) * 180 / n.
To calculate the size of an interior angle, divide the sum of interior angles by the number of sides. The sum of exterior angles is also calculated using the formula (n – 2)180∘ n, where n is the number of sides of the regular polygon.
The sum of the interior angles of a polygon of ‘n’ sides can be calculated using the formula 180(n-2)°. Each interior angle of a regular polygon of ‘n’ sides can be calculated by dividing the sum of the interior angles by the number of sides.
In summary, the sum of interior angles in a regular polygon can be calculated by multiplying the number of triangles formed inside the polygon by 180 degrees.
