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