Heptagon - Wikipedia
In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle.

Heptagon – Definition, Shape, Properties, Formulas - Math Monks
A heptagon is a polygon with seven sides and seven angles. The term ‘heptagon’ is derived from the Greek words ‘hepta’ meaning seven and ‘gon’ meaning sides. A heptagon is also known as 7-gon or septagon (‘septa’ means seven in Latin). Heptagon.

Heptagon - Definition, Properties, Types, Formula and Example
A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon. In Geometry, the shape that is bounded by at least three straight lines or at least three interior angles is called polygon. The most common examples of polygons are.

What is a Heptagon? A heptagon is a two-dimensional shape with 7 sides and 7 angles. It belongs to the class of polygons in two-dimensional geometry. Polygons are closed shapes made up of straight lines and no curves. “Hepta” means seven and “gonia” means angle in the Greek language.

Heptagon - Math.net
A heptagon is a polygon that has seven sides (Hepta- means seven) and seven interior angles. A heptagon is also sometimes called a septagon. What is a heptagon. A heptagon is defined as a 7-sided, closed, two-dimensional shape. Heptagons are present in real life.

Heptagon | Definition, Sides, Angles (Regular & Irregular) - Tutors
A heptagon is a 7-sided polygon with 7 interior angles that sum to 900°. The name heptagon derives from the Greek words hepta- for seven and gon- for sides. A heptagon is also called a 7-gon or septagon ( septa- is Latin for seven).

Mastering Heptagons – A Beginner’s Guide - The Story of Mathematics
A heptagon is a geometric figure that belongs to the broader category of polygons. Polygons are closed, two-dimensional shapes composed of straight lines. While it may seem like just another simple geometric shape, the heptagon presents fascinating complexities in its properties, historical uses, and real-world applications.

What is a Heptagon? A heptagon is a seven-sided polygon that has seven angles, seven vertices, and seven edges. They may have the same or different dimensions of length. It is a closed figure and a heptagon with all equal seven sides is called a regular heptagon. Let’s observe the figure given below that shows a heptagon. Heptagon Sides.

Heptagon -- from Wolfram MathWorld
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.

What is a Heptagon in Math? (Definition, Shape, Examples) - BYJUS
Heptagons have seven sides, seven angles and seven vertices. In a regular heptagon, all the sides and angles are congruent. The sum of all interior angles is 900°, and each angle of the regular heptagon is 128.57 in degrees and \ ( \frac {5\pi} {7}\) in radians.
