GM || HL are parallel so
angleMGH=GHL (ALT. INT. ANGLES)
and ANGLE mgh =agm...(1) (given angle bisector)
ANGLE ghl=lhd...(2) (give)
Now,agm =lhd from 1 and 2}
Hence AGM AND LHD ARE ALT. INT. Anlgle for lines ab and cd and gh is transversal.
Hence AB || CD

HEY MATE ⭐⭐⭐
HERE'S THE ANSWER ✌
_________________
⬇⬇⬇
GIVEN: GM is parallel to HL
so,
angle MGH=angle GHL
(alt. interior angles)
angle MGH= angle AGM.... i
(angle bisector)
angle GHL=angle LHD...... ii
now, AGM=LHD from i and ii
=>AGM and LHD are alternate interior angles for lines ab and cd
Hence,AB ll CD....... PROVED
