Heptagon

A heptagon is a polygon with seven sides and seven angles. The sum of the interior angles of a heptagon is always 900 degrees. Each interior angle of a regular heptagon measures 128.57 degrees. A heptagon can be regular or irregular.

Regular Heptagon

In a regular heptagon, all sides are of equal length, and all angles are of equal measure. The formula to calculate the measure of each interior angle in a regular heptagon is: Interior Angle = 180 * (n - 2) / n, where n is the number of sides, in this case, 7.

Irregular Heptagon

An irregular heptagon has sides and angles of different lengths and measures. The sum of the exterior angles of any polygon, including a heptagon, is always 360 degrees.

Properties

• A heptagon has 7 sides and 7 angles.
• The sum of the interior angles of a heptagon is 900 degrees.
• The sum of the exterior angles of a heptagon is 360 degrees.
