Question

Find the angles of a rhombus in which a diagonal length is equal to the length of a side.

Answer 1

It is the shape of two equilateral triangles with a common side. The larger angle is 120°; the smaller one is 60°.

Answer 2

We can draw the figure as shown in attachment.

Then you can see an equilateral triangle ABD.

So here angle A, B and D all will be 60 degrees.

So one of the angles of rhombus becomes 60°.

Rhombus is a parallelogram.Hence the adjacent angle becomes 120°.

Finally,angles of rhombus are 60 ,120,60,120.
