What additional information do you need to prove abc=def by the sas postulate ab=de bc=ef ac=df

SAS congruence requires the congruence of two sides and the angle between those sides.
On the picture is given that DF=AC and ∠D=∠A. Angle D lies between DF and DE, angle A lies between AC and AB, Hence you should add AB=DE.
correct choice is 1.
