The number of lines joining the angular points = 7 C 2 = \(\frac{7\times6}{1\times}=21.\) But the number of sides = 7 ∴ The number of diagonals = 21 – 7 = 14. (ii) Number of diagonals in a polygon of n sides = n C 2 – n ...

The diagonal of a polygon is a line segment obtained by connecting two opposite angles or non-adjacent vertices. The number of diagonals and their properties are different, based on the number of edges, based on the type of polygon. If the number of sides of a polygon is n, the number of diagonals that can be displayed is given by n (n – 3) 2.

Heptagon. Heptagon is a two-dimensional shape with seven angles, seven vertices, and seven edges. This seven-sided polygon “heptagon” is made up of two words ‘Hepta’ and ‘Gonia’, which means seven angles. Another name given to it is septagon or 7-gon. A heptagon has fourteen diagonals.

Formula for Number of Diagonals of a Polygon. This equation is obtained by adding the number of diagonals that each vertex sends to another vertex and then subtracting the total number of sides from it. For example, in a pentagon the total number of sides is five. Hence, the number of diagonals in them are 5 (5-3)/2 = 5.The formula obtained by subtracting n using nC2 methods is \ [\frac {n (n-3)} {2}\]. The total sides of a hexagon, for example, are six. As a result, the total diagonals are 6 (6-3)/2 = 9. Let’s know what a diagonal is. A diagonal of a polygon can be defined as a line segment joining two vertices.

A cube is a three-dimensional solid figure, also known as a square solid that has edges of the same length. This means that the length, width, and height of a cube are equal, and all its faces are squares. The body diagonal of a cube is the line segment that cuts through its center, joining the opposite vertices.

Definition. A line segment joining the two vertices or corners of the non-adjacent sides of a polygon is known as a diagonal. The corners must be opposite to each other for a diagonal. It is not a part i.e. side of a polygon. Figure 1 shows the demonstration of diagonals in different colors.

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.
