how to find the length of a diagonal line in a parallelogram Diagonals of a parallelogram are the segments which connect the opposite corners of the figure Where p q are the diagonals a b are the parallel sides LARGE p sqrt a 2 b 2 2ab cos A sqrt a 2 b 2 2ab cos B
In a parallelogram the diagonals bisect each other so you can set the labeled segments equal to one another and then solve for Then substitute 4 8 for in each labeled segment to get a total of 11 2 for the diagonal length How can we calculate the length of diagonals of a parallelogram The length of the diagonal of the parallelogram can be calculated by using the following formulas p x 2 y 2 2 x y c o s A x 2 y 2 2 x y c o s B q x 2 y 2 2

The formula to find the length of diagonals in a parallelogram is based on the lengths of the sides and the angle between them For a parallelogram with sides of lengths a and b and an included angle the diagonals p and q are given by the formulas p a b 2ab cos q a b 2ab cos To find the length of a diagonal we can rearrange the formula as follows A C A B 2 B C 2 C D 2 D A 2 B D 2 Similarly B D A B 2 B C 2 C D 2 D A 2 A C 2 We can use this formula to determine the length of either diagonal of a parallelogram if the lengths of its sides are known Step by Step Process for Finding
