Question

one of the digonal of rhombus is congrunt to one side find the side of rhombus​

Answer 1

Answer:

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

Let ABCD is a rhombus in which

AB = BC = DC =  on diagonal CA

In △ABC

AB=BC=CAB=60∘

∠D=∠B=60∘

angle A=180∘−angleB=180∘−60∘−120∘

∠C=angleA=120
