A polygon has 90 diagonals

Before going to learn the diagonal of a polygon formula, let us recall what is a polygon and what is a diagonal, a polygon has 90 diagonals. A polygon is a closed shape made with 3 or more line segments, A diagonal of a polygon is a line segment that is obtained by joining any two non-adjacent vertices.

A polygon has 90 diagonals

In Geometry, diagonals of a polygon are line segments joining two non-adjacent vertices. A square given below has two pairs of non-adjacent vertices. By joining the vertices of these two pairs, we get two diagonals of a square. Hence, AC and BD are diagonals of a square. The formula to find the diagonal of a polygon square is:. We can use this formula to find the diagonals of a polygon with any number of sides. In this article, we will discuss the diagonals of a polygon formula and the formula to find the number of diagonals in a polygon. A simple closed figure made up of line segments is known as a polygon. Polygons are generally classified according to the number of vertices and sides they have. For example, a triangle is a polygon with 3 sides and 3 vertices, similarly, a quadrilateral is a polygon with 4 vertices and 4 sides. Can you think of the number of diagonals of a quadrilateral, heptagon, hexagon, octagon, nonagon, etc?

Diagonals of a square are the line segments joining opposite vertices. A flat, closed shape with four equal sides, four vertices like craft paper, a photo frame , and four right angles is known as a square. Take a look at the square craft paper shown below. The two lines are called diagonals of a square. The diagonal of a square is a line that connects one corner to the opposite corner through the center. A square has two diagonals that are equal in length. They bisect each other at right angles.

A polygon has 90 diagonals

A diagonal is a line segment that joins one corner vertex of a polygon to another but is not an edge side. In other words, it joins any two non-adjacent vertices of a polygon. So, we can draw the diagonals in a polygon when we directly join any two vertices which are not joined by any side.
