Heptagon - Wikipedia
In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of septua-, a Latin -derived numerical prefix, rather than hepta-, a Greek -derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle.

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

Heptagon – Definition, Shape, Properties, Formulas
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.

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.
