Interior Angle Math Is Fun
In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint. for a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle) if a point within the angle is in the interior of the polygon. Interior angle 1. any of the four interior angles angles formed between two straight lines intersected by a third straight line. 2. an angle formed inside a polygon by two adjacent sides.

Sum of all the interior angles of a polygon is equal to the product of a straight angle and two less than the number of sides of the polygon. in a regular polygon, all the interior angles measure the same and hence can be obtained by dividing the sum of the interior angles by the number of sides. sum of interior angles = (p 2) 180°. The sum of the exterior angles of any polygon is 360°. the sum of the interior angles of an n-sided polygon is (180 n − 360)°. regular polygons. each exterior angle of an n-sided regular polygon is 360° ÷ n. each interior angle of an n-sided regular polygon is 180° − 360° ÷ n. interactive animation showing why exterior angles add up.
