# How many sides are in a heptagon

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.

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. There are two types of heptagons based on their shapes. They can be seen below.

## How many sides are in a heptagon

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. This can be seen by subdividing the unit-sided heptagon into seven triangular "pie slices" with vertices at the center and at the heptagon's vertices, and then halving each triangle using the apothem as the common side. As 7 is a Pierpont prime but not a Fermat prime , the regular heptagon is not constructible with compass and straightedge but is constructible with a marked ruler and compass. It is the smallest regular polygon with this property. This type of construction is called a neusis construction. It is also constructible with compass, straightedge and angle trisector. An approximation for practical use with an error of about 0. Draw arc BOC. There are other approximations of a heptagon using compass and straightedge, but they are time consuming to draw. The regular heptagon belongs to the D 7h point group Schoenflies notation , order The approximate lengths of the diagonals in terms of the side of the regular heptagon are given by. Apart from the heptagonal prism and heptagonal antiprism , no convex polyhedron made entirely out of regular polygons contains a heptagon as a face. A regular triangle, heptagon, and gon can completely fill a plane vertex. However, there is no tiling of the plane with only these polygons, because there is no way to fit one of them onto the third side of the triangle without leaving a gap or creating an overlap.

A heptagon is a polygon that has seven sides Hepta- means seven and seven interior angles. A heptagon is also sometimes called a septagon. A heptagon is defined as a 7-sided, closed, two-dimensional shape. Heptagons are present in real life. Two real-life heptagon examples include the fifty pence and twenty pence coins in the UK. A regular heptagon is a heptagon whose sides and interior angles are all equal in measure. The figure below shows a regular heptagon example:. An irregular heptagon is a heptagon that has varying measures of sides and interior angles.

### How many sides are in a heptagon

Heptagon is a two-dimensional shape with seven angles, seven vertices, and seven edges. Another name given to it is septagon or 7-gon. A heptagon has fourteen diagonals. A polygon is a closed two-dimensional shape made up of straight sides having any number of sides. In simple words, we can say that a heptagon is a polygon with 7 sides. In this article, we will explore the properties and shape of the heptagon.
