Lengths of Diagonals in Regular Polygons

As regular polygons equal sides and interior angles, we can find the formula for the length of regular polygons. The formula for the length of the diagonal of a regular polygon is given as:

Where,

  • d is the length of diagonal,
  • s is the length of the side, and
  • n is the number of sides of the polygon.

Diagonal of a Polygon Formula

Diagonals of a polygon are the lines that connect the alternate vertices of the polygon. A polygon of n sides has n(n-3)/2 diagonals. A polygon is a closed figure with n sides (where n is always greater than equal to 3). A polygon is a closed shape with three or more straight sides, and diagonals are the line segments that connect any two non-adjacent vertices of the polygon.

In this article, we’ll explore the concept of diagonals in polygons, examine their properties and patterns, and discuss their applications in various fields. So, let’s get started and dive into the exciting world of polygons and diagonals!

What are Polygons?

Polygon can be defined as a closed figure which is formed by joining the straight lines. So it is easy to see that to make a polygon at least three lines are needed. There are polygons known with different names depending on the number of lines by which it is formed. Some basic polygons are:...

Number of Diagonals in a Polygon

As we know there are different polygons with each having a different number of sides, such as a triangle with three sides, quadrilateral with 4 sides, a pentagon with five sides, etc., and each polygon has a different number of diagonals....

Properties for Diagonals of a Polygon

There are various properties diagonals are associated with for various different polygons such as different types of quadrilaterals and regular polygons. Some of polygons with various different properties of diagonals are:...

Diagonals in Convex and Concave Polygons

Convex and concave polygons are defined based on the position of diagonals. If all the diagonals of a polygon lie inside of the area bounded by its side, then it is called a convex polygon whereas if any one of the diagonals of a polygon lies outside of the area bounded by its side, then it is called a concave polygon....
