A regular pentagon is any five-sided polygon where all the sides and angles are equal. Each angle is _____?
Answer: 108°
Explanation
The formula for the interior angle of a regular polygon is (180° × (n - 2)) / n, where n = 5 for a pentagon.
Substituting n = 5, we get (180 × 3) / 5 = 108° per angle.
