Question

diagonal db of a rhombus abcd is equal to one of it's sides the value of angle a​

Answer 1

Answer:

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°
