We also know that both of these triangles, both triangle DCA and triangle BAC, they share this side, which by reflexivity is going to be congruent to itself, so in both triangles, we have an angle and a side that are congruent, but can we figure out anything else? But it turns out, given the information that we have, we can't just assume that because something looks parallel, that, or because something looks congruent that they are, and so based on just the information given, we actually can't prove congruency.
