An octagon is a geometric shape that possesses eight sides and eight angles. Derived from the Greek words "okto" meaning eight and "gonia" meaning angle, the term octagon accurately describes this polygonal figure. Each of the sides in the octagon is equal in length, resulting in a symmetrical figure. Its angles are also equal and measure 135 degrees each, providing a consistent and balanced structure.
Considered a regular polygon due to its uniformity, an octagon can be formed by connecting the endpoints of a square. It can also be observed as an intermediate shape between a hexagon and a decagon. Due to its simple yet elegant design, the octagon finds numerous applications in various fields. In architecture, it serves as a fundamental shape in the design of buildings, windows, and doors, lending a sense of symmetry and stability. Similarly, it finds utility in the realm of design, appearing in the creation of logos, symbols, and patterns.
Moreover, the octagon holds significance in sports, particularly in martial arts and combat sports. An octagonal ring or cage is commonly used in events such as mixed martial arts (MMA) competitions, providing a defined area for bouts and creating an engaging spectacle for spectators. In summary, an octagon denotes a polygonal shape with eight symmetrical and equal sides and angles, contributing to its versatility and widespread use in math, design, architecture, and sports.

The word "octagon" is derived from two Greek words: "okto", meaning "eight", and "gonia", meaning "angle". When combined, they form "oktagōnon", which evolved into the Latin word "octagonum". Eventually, this Latin term was adopted into Middle French as "octagone" and then into English as "octagon".
