The term for a seven-sided polygon is "heptagon." This word is derived from the Greek prefix "hepta," which means seven, combined with the suffix "gon," which comes from the Greek word for angle. Therefore, a heptagon is characterized by having seven angles and seven sides.

In contrast, a hexagon refers to a six-sided polygon, an octagon describes an eight-sided polygon, and a pentagon is a five-sided polygon. Understanding these definitions and the roots of the terms helps clarify why "heptagon" is the correct choice for a seven-sided figure.
