Geometry Angles Of Polygons 8th Grade Math Youtube In this lesson we demonstrate how to determine the sum of the angles of polygons. In a summer school edition of yay math, we wade into understanding polygons, and name a bunch of them from 3 sides up to 12.then, we find the number of trian.

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. 2. sum of interior angles: the sum of interior angles in any polygon can be determined using the formula: sum of interior angles \(= (n 2) \times 180^\circ\) where \( n \) is the number of sides in the polygon. 3. each interior angle of a regular polygon: a regular polygon has all its sides and angles equal. the measure of each interior angle.

Each interior angle = { (n − 2) × 180°} ⁄ n. example 1. find the measure of each exterior angle of a regular polygon having 9 sides. solution. each exterior angle of a regular polygon having 9 sides = 360° ⁄ 9 = 40°. example 2. find the measure of each interior angle of a regular hexagon. Each side must intersect exactly two others sides but only at their endpoints. the sides must be noncollinear and have a common endpoint. a polygon is usually named after how many sides it has, a polygon with n sides is called a n gon. e.g. the building which houses united states department of defense is called pentagon since it has 5 sides.
