What are Diagonals?
In geometry, a diagonal is a straight line segment, which joins two vertices (corners) of a polygon that are not adjacent to each other. It is the simplest definition, the line is from one corner of a closed shape to the opposite corner which is not along its side. The smallest possible polygon which has a diagonal is the quadrilateral (square, rectangle, etc.). A triangle does not have any diagonal.
Real Life Application of Diagonals
Diagonals are straight lines connecting the opposite corners of a polygon. Diagonals for curved shapes, such as circles, spheres, cones, etc, can also be easily found. Diagonals have various applications and uses in various real-life scenarios and some of them are discussed below.
Here, we will discuss definition of diagonal and the different ways diagonals are used in various fields and industries.
