![]() ![]() Let us study diagonal formula for different shapes We have a number of diagonals formula of a polygon which help us to know the number of diagonals in a polygon that is ![]() The shapes with a diagonal drawn on them are given below: A quadrilateral, the next-simplest, has two diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle. A segment whose endpoints are nonadjacent vertices is called a diagonal.Ī diagonal of a polygon is a line from a vertex to a non-adjacent vertex. Segments that share a vertex are called adjacent sides. The points at which the segments meet are called vertices. The segments are referred to as the sides of the polygon. Triangles, square, rectangle, pentagon, hexagon, are some examples of polygons. To recall, a two-dimensional closed figure bounded with three or more than three straight lines is called a polygon. We can calculate the length of rectangle (l) when its diagonal (d) and width (w) is given using the formula, l = √(d 2 - w 2).We have studied what a polygon is. How to Find the Length of Rectangle When The Diagonal of Rectangle is Given? We can calculate the area (A) of a rectangle when its diagonal (d) and length (l) is given using the formula, Area = l × √(d 2 - l 2). How to Determine the Area of Rectangle When Diagonal of Rectangle is Given? The diagonals of a rectangle bisect each other but not at 90 degrees angle. A rectangle is also a parallelogram where the opposite sides are equal. Since a rectangle is a quadrilateral, all the angles are right angles. The diagonals of a rectangle bisect each other and are equal.
