Heptagon - GCSE Maths Definition

A heptagon is a type of polygon that has seven straight sides and seven angles. The word "heptagon" comes from Greek, where "hepta" means seven and "gon" means angle. In a regular heptagon, all sides are of equal length, and all angles are equal too, each measuring about 128.6 degrees. However, not all heptagons are regular; some can have sides or angles that are different sizes. Heptagons can be found in various shapes and are an important part of studying geometry because they help us understand properties of shapes with more than four sides. Remember, when you count the sides, angles, or vertices of a heptagon, you'll always find seven.
