# Septagon vs. Heptagon: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Updated on September 28, 2023
A septagon and a heptagon are synonymous geometric terms, both referring to a polygon with seven sides and seven angles.

## Key Differences

A septagon and a heptagon are identical geometric figures, each characterized by having seven straight sides and seven angles. The terms "septagon" and "heptagon" are interchangeable, with "septagon" derived from the Latin word "septem," meaning seven, and "heptagon" from the Greek word "hepta," also meaning seven. While they represent the same shape, the distinction in naming stems from the differing origins of the words.

Despite having different names, a septagon and a heptagon have the same geometric properties and characteristics. Both polygons are classified as heptagons and can be regular or irregular. A regular septagon or heptagon has all its sides and angles equal, whereas an irregular one does not have equal sides and angles. Regardless of the nomenclature, the geometric principles applicable to a septagon are equally applicable to a heptagon.

Septagon and heptagon are versatile terms used in various mathematical and real-world contexts to describe seven-sided polygons. The choice between the terms depends on individual preference or contextual appropriateness, and they are used interchangeably in mathematical geometry to study the properties, dimensions, and other attributes of seven-sided polygons. Both terms are integral to geometry, enabling a more profound understanding of polygonal structures and their applications.
