    we want it to be a parallelogram. only opposite sides of a parallogram have to be congruent, but thats not really going to be used here

    Well, if DAB = 40º, and DCB = 40º then ADC = ABC which makes it a parallelogram right?

    DC and AB are congruent angles tho right? so if ABC = DCB then ADC = CBA which means DC = AB and DA = BC
