Question

What is formula for determining sum of angles in polygon?​

Answer 1

Answer:

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

Answer 2

The formula for determining sum of interior angles in polygon is -

(n-2)×180

where n= no of sides of polygon.
