If the sum of the interior angles of a regular polygon is equal to the sum of its exterior angles, determine the number of sides in the polygon.
Show answer & explanation
Correct answer: C
Explanation
Sum of interior angles = (n − 2) × 180°
Sum of exterior angles = 360°
(n − 2) × 180 = 360
⇒ n − 2 = 2
⇒ n = 4
