ABCD is a rhombus whose one angle is `60^@`.prove that the ratio of length of its diagonal is `sqrt3:1`

Assertion (A) : If ABCD is a rhombus whose one angle is 60^(@) then the ratio of the lengths of its diagonals is sqrt3 : 1 Reason (R ) : Median of a triangle divides it into two triangle of equal area.

In a rhombus ABCD, angleA = 60^(@) and AB = 6 cm . The length of the diagonal BD is equal to

In a rhombus ABCD, length of each side is 10 cm and angle A = 60^(@) . Find the lengths of its diagonals AC and BD.

Prove that the are of the rhombus is half the product of the lengths of its diagonals.

A rhombus with one side-3 meters and one angle 60^@ is given in the picture. Find the sum of the length of its diagonals

Area of a rhombus is 144 cm^(2) and the ratio of length of two diagonals is 1:2. The sum of lengths of its diagonals are :
