Answer»

Given,

AD = BC - - - - - - - - - - - 1 (given)

∠DAB = ∠CBA - - - - - - - - - - 2 (given)

AB = AB - - - - - - - - - - - - - - - 3 (common)

1)) ΔABD ≅ ΔBAC

By C.P.C.T we can say that all angles and sides of a triangle will also be equal

2))BD = AC

By C.P.C.T, we can say that BD = AC

3))∠ABD = ∠BAC

By C.P.C.T, we can say that ∠ABD = ∠BAC
