The diagonal from B to D is drawn in parallelogram ABCD. Which of the following methods can NOT be used to prove ΔDAB≅ΔBCD?
SSS
SAS
SSA
ASA
SSA is not a congruence condition. So, it can not be used to prove congruency, all the other conditions can be.
In parallelogram ABCD, AP and CQ are perpendicular to diagonal BD. It can be proved that ΔAPB ≅ ΔCQD.
In △ABC and △XYZ, if BC = YZ, ∠ABC=∠XYZ and ∠ACB=∠XZY,, then by which postulate is △ABC≅△ZXY ?
