What is a Heptagon?
The shape of heptagon is defined as a seven-sided polygon, also known as a septagon. Each of its sides is a straight line, and the sum of its internal angles is 900 degrees. Heptagons can be regular, with all sides and angles equal, or irregular, with varying side lengths and angles. The regular heptagon is often used in mathematical problems and geometric designs due to its symmetrical properties.
Properties of a Heptagon
The properties of heptagons are determined by their side lengths and angles. In a regular heptagon, all sides are equal, and each internal angle measures approximately 128.57 degrees. Heptagons can be both convex, with all vertices pointing outward, or concave, with at least one vertex pointing inward. These properties affect how heptagons are used in practical applications and theoretical studies.
Regular vs. Irregular Heptagons
Regular heptagons are characterized by their equal side lengths and angles, making them ideal for symmetric designs. Irregular heptagons, on the other hand, have sides and angles of different lengths, offering more flexibility in creative and architectural designs. Both types of heptagons are valuable in different contexts, depending on the desired outcome of the design or study.
Convex and Concave Heptagons
Convex heptagons are the most common type, with all interior angles less than 180 degrees, ensuring that all vertices point outward. Concave heptagons, however, have at least one interior angle greater than 180 degrees, creating a vertex that points inward. This classification is important for understanding how heptagons interact with other geometric shapes and structures.
How to Draw a Heptagon?
Drawing a heptagon can be accomplished using a compass or by freehand sketching. For a regular heptagon, a compass is the best tool to ensure equal side lengths and angles. Start by drawing a circle, and then divide the circle into seven equal parts using a protractor. Connect the points where the divisions intersect the circle to form a heptagon.
Using a Compass
- Draw a circle with a compass.
- Divide the circle into seven equal arcs.
- Connect the intersections to form a heptagon.
Freehand Drawing
For those without a compass, freehand drawing is an alternative, though it may lack precision. Begin by sketching a rough circle, then estimate the division into seven parts. Carefully draw straight lines connecting the points to form the heptagon.

Area = (7/4) x side length² x cot(π/7)
Area of Regular Heptagons
To calculate the area of a regular heptagon, simply substitute the side length into the formula. This calculation provides an accurate measurement of the heptagon's total area.
Area of Irregular Heptagons
The area of an irregular heptagon can be more complex to calculate, as it requires dividing the shape into smaller triangles and calculating the area of each triangle individually. This method provides a close approximation of the heptagon's total area.
