Verified answer

If the length of one side of a rhombus is equal to the length of one diagonal, find the angles of the rhombus.

Let the angle be x

Now,

Let ABCD be a rhombus such that the length of its diagonal BD is equal to the length of one of its sides.

That is, AB = BC = CD = AD = BD

ABD is an equilateral triangle.

So,

BAD = 60

60 + x = 180°

x = 180 - 60

x = 120° ans
