Find the measure of the interior angles of a 5-sided regular polygon?
- 112°
- 108°
- 106°
- None of these
Explanation
The sum of the interior angles of a polygon is given by:
(n - 2) × 180
where n is the number of sides.
For a 5-sided polygon (pentagon):
(5 - 2) × 180 = 3 × 180 = 540
Since it's a regular polygon, all interior angles are equal. To find each angle:
540 ÷ 5 = 108°
