Answer: AB = DC (Opposite sides of a parallelogram are equal)

AB = BE (Given)

Therefore, BE = DC

IN TRIANGLES QEB AND QCD: Angle DQC = Angle EQB (vertically opposite angles are equal)

Angle BEQ = Angle CDQ (Alternating interior angles are equal)

BE = DC (Proved)

Therefore Triangle QEB is Congruent to Triangle QCD by AAS criterion.

Therefore, QC = QB

Therefore, QC:QB = 1
