Question

ABCD is a quadrilateral in which AB||DC and AD|| BC.Find<b,<c and <d.​

Answer 1

Step-by-step explanation:

Given;

ABCD is an quadrilateral.

AB||DC.

AD||DC.

<A= 50.

so ,as opposite sides are parallel so it's a parallelogram.

now,

<A= <C (Opposite Angeles)

<A= <C= 50° .

and, <A+<D=180°(interior angles are supplementary)

= 50+<D= 180.

= <D= 180- 50= 130°.

and, <D= <B(opposite angles).

<B= 130°.

hence , we have got all the values;

<A= <C= 50°.

<B=<D= 130°...(ANS)..
