Heptagon

A heptagon is a polygon with seven sides and seven angles. The sum of the interior angles of a heptagon is 900 degrees.

Properties of a Heptagon:

1. A heptagon has 7 sides and 7 angles.
2. The sum of the interior angles of a heptagon is 900 degrees.
3. The exterior angles of a heptagon add up to 360 degrees.
4. A regular heptagon has all sides and angles equal in measure.

Formulas for Heptagon:

Sum of interior angles = (n - 2) * 180°, where n is the number of sides

Sum of exterior angles = 360°

Sample Questions:
