17. ABCD is a parallelogram. The sides AB, ADare produced to E, F so that AB = BE and AD =DF. Prove that the triangles BEC and DCF arecongruent..... please answer ASAP ....​

Answer»

Given:

AB = BE = CD  and  BC = AD = DF

in a Parallelogram ∠BAD = ∠CDF

in Parallel Lines (CONGUGATE ANGLES) ∠EBC = ∠BAD

So, ∠BAD = ∠CDF = ∠EBC

To Prove :

ΔBEC ≅ ΔDCF

Proof :

Side -> EB = CD

Angle -> ∠CDF = ∠EBC

Side -> BC = DF

Hence, Through SAS ΔBEC ≅ ΔDCF
