A heptagon is a polygon with seven sides. The word “heptagon” comes from the Greek words “hepta,” meaning seven, and “gonia,” meaning angle. Therefore, a heptagon has seven sides and seven angles.
In a regular heptagon, all sides are of equal length, and all interior angles are equal. Each interior angle of a regular heptagon measures approximately 128.57 degrees. The sum of all interior angles in a heptagon is 900 degrees.
Heptagons can be found in various real-world applications, such as in architecture and design, where their unique shape can be used to create interesting and aesthetically pleasing structures.
