Question

In the adjoining figure, ABCD is a quadrilateral
in which AD = BC and DAB = CBA. Prove
that
(1) ABD = ABAC
(ii) BD = AC
(iii) ABD = BAC.​

Answer 1

Answer:

Step-by-step explanation:

As it's adjacent angles are equal it is a rectangle.

1)sol Question is improper

2)sol As it is a rectangle it's diagnols are also equal.

        So, BD = AC

3)sol As it is a rectangle it's all sides are equal. That means it's all angles are

        90°.

        So, ∠ABD = ∠BAC
