Answer 1

Hey Mate !!!!

From the given question,

GIVEN : We are given that ABCD is a parallelogram

              i.e. AD = BC (∵ opposite sided of a parallelogram are equal)

              i.e. AB = DC

And BD is the diagonal.

TO SHOW : ΔBAD≅ΔDCB

PROOF :

In ΔBAD and ΔDCB

AD = BC (∵ opposite sided of

AB = DC   a parallelogram are equal)

BD = BD (common)

∴ By SSS congruence criteria,

ΔBAD≅ΔDCB

Hence Proved !!
