Answer 1

Sample response: Any polygon can be broken into triangles. There are two less triangles than the number of sides in the polygon. You can multiply the number of triangles formed by 180° to find the sum of the interior angles. The sum can be written as (n – 2)180, where n is the number of sides.

Answer 2

(n-2) × 180°

Explanation:

Sum of interior angles for a polygon = (n-2) × 180°
