Question

one of the diagonal of a rhombus is equal to one of its sides find the angles of the Rhombus​

Answer 1

All the sides of a rhombus are equal. So if one diagonal is equal to one side, we have 2 equilateral triangles with a common base. Hence all the angles of the 2 triangles are 60 degrees each. Thus one pair of opposite angles of the rhombus is 60 degrees and the other pair 120 degrees.

Answer 2

As the diagonal is congruent to the side ... we get equilateral triangles.... each equilateral triangle is 60 degree... so one angle will become 120 degree...

so your answer is 120 degree .

Thus the angles of the rhombus are 120, 60 , 120,60 degrees respectively...
