8 1 Angle Sums Of Any Polygon Youtube We discuss the sum of the interior and exterior angles of polygons. we also discuss regular vs irregular and convex vs. concave polygons. Scroll down the page for more examples and solutions on the interior angles of a polygon. example: find the sum of the interior angles of a heptagon (7 sided) solution: step 1: write down the formula (n 2) × 180°. step 2: plug in the values to get (7 2) × 180° = 5 × 180° = 900°. answer: the sum of the interior angles of a heptagon (7. The angle sum property formula for any polygon is expressed as, s = ( n − 2) × 180°, where 'n' represents the number of sides in the polygon. the angle sum property of a polygon states that the sum of the interior angles in a polygon can be found with the help of the number of triangles that can be formed inside it. Solution: the sum of the exterior angles of a regular polygon is 360°. therefore y 2y 3y 4y 8y = 360°. ⇒ 18y = 360°. ⇒ y = 360° 18. ⇒ y = 20°. the size of the largest exterior angle = 8 × y = 8 × 20° = 160°. we know that the sum of an exterior angle and its adjacent interior angle = 180°.
