Find the angle of a rhombus ABCD if side AB is equal to its diagonal AC.

Q If in a rhombus ABCD diagonal AC is equal to side
AB then what is its angle?
.
and.- since ABCD is a Rhombus then
AB=BC=CD=DA
but from the question AC=AB
therefore, AC=BC also
I.e.AB=BC=AC
I.e ABC is isosceles triangle
therefore <ABC=<BCD=<BAC=60°
and in the same way <D=<DAC=<ACD=60°
then <A=<C=120°(by adding the adjoining angle)
and <B=<D=60°
ask us if you have any question in your mind
