Question

What is the formula for finding the sum of interior angles of a polygon with n sides?

विकल्प

• n × 180°

• (n − 2) × 180°

• (n + 2) × 180°

• (n − 1) × 180°

Answer 1

(n − 2) × 180°

Explanation:

This is the standard formula where n represents the number of sides of the polygon, and (n − 2) gives the number of triangles formed.
