# What is the sum of the measures of the interior angles of a heptagon?

The angles that lie inside a shape (generally a polygon) are said to be interior angles** **and a heptagon is defined as a polygon with 7 sides.

## Answer: The sum of the measures of the interior angles of a heptagon is 900^{º}.

The formula to find the sum of the measures of the interior angles of a polygon is (n - 2) × 180^{°}, where n is a number of sides.

**Explanation:**

Sum of the measures of the interior angles of a heptagon = (n - 2) × 180^{º}

= (7 - 2) × 180^{º}

= 5 × 180^{º}

= 900^{º}
