Thus, they are also called congruent diagonals.Įach diagonal bisects the other. The diagonals of a square are of the same length. The diagonal of a square is the line segment that is drawn between its opposite corners. You will use diagonals not only in Math but also in your everyday life!Ī square has two diagonals. Huge steel rods are also placed diagonally in very tall or heavy buildings to prevent them from falling or crashing on itself. We put rods diagonally in an empty frame to stabilize it and keep it from breaking. Similarly, we can calculate for the other polygons.ĭiagonals make the framework or base for any structure. Therefore, there are 9 diagonals present in a hexagon. Number of diagonals= (n(n-3))/2 where n is the number of vertices of the polygonĮxample- To calculate the number of diagonals of a hexagon, we take n=6 (because it has 6 vertices) There is a simple formula to determine the number of diagonals in a polygon. The number of diagonals of a polygon depends on the number of sides it has.
(plural- vertices) It is described as the corner of any shape. Examples- square, triangle, rectangle, decagon. The corners of a polygon are connected by line segments. It is a plane figure with three or more sides and angles. Here you can read about diagonals, the formula to calculate the number of diagonals, diagonal of square formula, diagonal of rectangle formula, diagonals of rhombus and parallelogram, and some fun properties of diagonals. A diagonal is defined as a line segment joining the two opposite vertices of a polygon.
