To find the sum of the interior angles of a heptagon, use the formula (n-2) times 180 over n, where n is equal to the number of sides of the polygon.
For a heptagon, which is a 7-sided figure, we plug in values to get (7-2) times 180, or 5 times 180 degrees, or 900 degrees.

The sum of the measures of the interior angles of a heptagon is 900 degrees.
900 degrees.Explanation: The sum of the measures of the interior angles of a heptagon is 900°. A heptagon has 7 sides. So to calculate the sum of the measures of the interior angles in a heptagon, substitute 7 for n in (n − 2) • 180°. You get (7 − 2) • 180°, or 5 • 180°= 900°.
A heptagon has 7 sides and 7 angles. The sum of the interior angles is 900°. If the heptagon is a regular heptagon, meaning all sides and angles are congruent, then the formula (180(n-2))/ n gives the individual interior angle measure. "n" is the number of sides in this case. In a regular heptagon, the interior angle measures 128 4/7 degrees.

The sum of the four interior angles is 360 degrees.
