The diagonals of rectangle are two heat segments that attach at two opposite vertices and are that the same size. The diagonals the the rectangle divide the rectangle right into two equal appropriate triangles. A rectangle is a two-dimensional number with four sides, 4 vertices, and four angles. Let us learn much more about the diagonals of a rectangle, your formula, and solve a few examples.

What space Diagonals the Rectangle?


The diagonal line of a rectangle is a line segment the joins any type of two of its non-adjacent vertices. A rectangle has two diagonals wherein each that the diagonals divides the rectangle right into two right-angled triangles through the diagonal being the hypotenuse. The diagonals bisect every other, one obtuse angle and also the other an acute angle.

Properties that Diagonals the Rectangle


The diagonals that rectangle are line segment drawn in between the the opposite vertices the the rectangle. The nature of diagonals of rectangle space as follows:

The 2 diagonals that a rectangle room congruent. In various other words, the length of the diagonals is equal.The 2 diagonals bisect every other and divide the rectangle right into two same parts.When the diagonals bisect each other, the angles of a rectangle end up being one obtuse angle and the various other an acute angle.Since the diagonals divide the rectangle right into two right-angled triangles, the is considered the hypotenuse of these triangles.

Diagonal of Rectangle Formula


The diagonal line of a rectangle formula help in recognize the length and also width of the rectangle. In the following rectangle, AC and also BD are the diagonals. You can see the the lengths that both AC and BD room the same. A diagonal cut a rectangle right into 2 right triangles, in i m sorry the sides space equal to the sides of the rectangle and with a hypotenuse. That hypotenuse is the diagonal.

*

Thus, to calculate the length of diagonals the a rectangle the formula is: d = √( l2 + w2)

Where,

d = diagonal line of rectanglel = size of the rectanglew = width of the rectangle

Diagonal of Rectangle Derivation


The diagonal line of a rectangle formula is derived using Pythagoras theorem. Permit us take into consideration a rectangle of length "l" and also width "w". Allow the length of every diagonal it is in "d".

*

Applying Pythagoras theorem come the triangle ABD,

d2 = l2 + w2

Taking square source on both sides,

d = √( l2 + w2)

Thus, the diagonal of a rectangle formula is:

d = √( l2 + w2)

Where,

l = length of the rectanglew = broad of the rectangle

Angles that Diagonals of Rectangle


The diagonals of a rectangle space of equal length and they bisect every other but do not kind right angle at the center. They form linear pairs of angles such together obtuse edge + acute angle at every of the diagonal. The rectangle is referred to as a square if that is diagonals bisect each various other at right angles together the diagonals that a rectangle perform not bisect the respective vertex angles right into equal angles. A diagonal divides a rectangle into two congruent triangles, the too best triangles with their hypotenuse being the same. Every diagonal acts as the hypotenuse for the best triangles so formed. Applying Pythagoras theorem come the triangle therefore formed, d2 = l2 + w2, whereby d is diagonal, l is length and w is the width of the rectangle. Taking square source on both sides, √(d2) = √( l2 + w2). Thus, the diagonal line of a rectangle formula is: √(l² + w²).

Listed listed below are a couple of interesting topics that are concerned the diagonals of a rectangle. Take a look.


Examples ~ above Diagonals that Rectangle


Example 1: using properties of angle of the rectangle, discover the diagonal line of a rectangle whose dimensions space 8 units and 6 units.

Solution:

The dimensions of a rectangle = 8 units and also 6 units.According to the nature of angle of the rectangle, the diagonal of a rectangle = (d) = √( l2 + w2)Length of diagonal line of rectangle = √(8)2+(6)2 = √100 = 10 units.

Therefore, the length of the diagonal of the rectangle is 10 units.


Example 2: The dimension of the display of a television is the length of the diagonal. Then discover the size of the tv whose dimensions space 18 inches and also 46 inches.

Solution:

The size of the television, l = 46 units.

The broad of the television, w = 18 units.

Using the diagonal line of a rectangle formula,

d = √( l2 + w2)

d = √( 462 + 182)

= √2440

= 49.39 inches.

Therefore, the dimension of the tv is 49.39 inches.


Example 3: If a rectangular board has actually a length of 13 inches v a diagonal line of 18 inches. What is the broad of the rectangle?

Solution:

The length of the board, together = 13 inches.

The diagonal of the board, d = 18 inches.

Using the diagonal of rectangle formula,

d = √( l2 + w2)

182 = (132 + w2)

w = √155

w = 12.4 inches.

Therefore, the broad of the rectangle is 12.4 inches.
