Answer:
given AB=EB THEREFORE A=E
BC=BD THEREFORE D=C
BC/BD=BE/BA(BY ALTARNATE OPPOSITE ANGLE)
A=C or E=D THEREFORE
IT IS AN PARLLEL LINE

Step-by-step explanation:
Given: BE =AB.
BC =BD.
To prove: AEllDC.
proof :
<ABE= <DBC........(i).( vertically opposit angle).
in∆ABE,
<BEA=<EAB......angle opp. equal side.
in∆BCD,
<BCD=<CDB........angle opp. equal side.
hence <AEB=<EAB=<BCD=<CDB.
hence by AAA congruency rule....
∆AEB is congruent to ∆BDC.
hence we had already proved that <AEB=<BDC....
so , we can conclude that , if two lines are parallel then alternate interior angles are equal ....
here we have proved these two angle as alternate interior. angle
so, AE ll DC
