Question

Angle sum property of polygon answer me fast

Answer 1

Hi friend,
here is your answer
let n = side
so n-2×180°
ex. angle sum of triangle
side =3= n
n-2×180°
3-2×180°
1×180°
180°

Answer 2

Step-by-step explanation:

Properties

The properties of polygons are based on its sides and angles.

The sum of all the interior angles of an n-sided polygon is (n – 2) × 180°.

The number of diagonals in a polygon with n sides = n(n – 3)/2

The number of triangles formed by joining the diagonals from one corner of a polygon = n – 2

The measure of each interior angle of n-sided regular polygon = [(n – 2) × 180°]/n

The measure of each exterior angle of an n-sided regular polygon = 360°/n
