Answer 2

Answer:

Hey here is ur Answer

Step-by-step explanation:

Ans. (i) In quadrilateral ABCD, we have AD = BC and

∠DAB = ∠CBA.

In ΔABD and ΔBAC,

AD = BC

[Given]

AB = BA

[Common]

∠DAB = ∠CBA

[Given]

∴ Using SAS criteria, we have ΔABD ≌ ΔBAC

(ii) ∵ ΔABD ≌ ΔBAC

∴ Their corresponding parts are equal.

⇒ BD = AC

(ii) Since ΔABD ≌ ΔBAC

∴ Their corresponding parts are equal.

⇒ ∠ABD = ∠BAC.
