In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon.

In this article, let’s discuss the seven-sided polygon called “Heptagon” with proper definition, shape, sides, properties along with its formula in detail.

Aug 3, 2023 · A heptagon is a polygon with seven sides and seven angles. The term ‘heptagon’ is derived from the Greek words ‘hepta’ meaning seven and ‘gon’ meaning sides.

What is a Heptagon? A heptagon is a two-dimensional shape with 7 sides and 7 angles. It belongs to the class of polygons in two-dimensional geometry. Polygons are closed shapes made up of straight lines and no curves. “Hepta” means seven and “gonia” means angle in …

Heptagon is a two-dimensional shape with seven angles, seven vertices, and seven edges. This seven-sided polygon “heptagon” is made up of two words ‘Hepta’ and ‘Gonia’, which means seven angles. Another name given to it is septagon or 7-gon. A heptagon has fourteen diagonals.

Heptagons are classified as regular or irregular and concave or convex. A regular heptagon is a heptagon whose sides and interior angles are all equal in measure. The figure below shows a regular heptagon example: A regular heptagon has the following properties: 7 interior angles measuring ~128.57° each. 7 exterior angles measuring 51.43° each.

May 25, 2023 · There are two main types of heptagons: regular and irregular. A regular heptagon has all sides and angles equal. It is both cyclic (all corners lie on a single circle, known as the circumcircle) and equilateral (all sides have the same length).

Apr 1, 2025 · A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.

Dec 11, 2024 · A heptagon is a seven-sided polygon characterized by its seven sides, seven angles, a total of 14 diagonals, and can be classified as regular or irregular based on side length and angle measurement.
