Best ResponseYou've already chosen the best response.0On the Diagram we know that the segments BC and AD are congruent, also that the angles BCD and angle ADC are congruent. Now, you might observe that both triangles have one same side, which is CD, and we can see it clear on the name of each: T.BCD and T.ACD the fact that two of their vertices coincide means that they share a side. Now, because they share the same side, we can establish the axiom of rectivity: \[CD=CD\] Now, we know that two sides and the angle between them are congruent, this being: \[BC=AD\] \[\angle BCD = \angle ADC\] \[CD=CD\] Now with that informaton we can use the SAS theorem of congruency and we can conclude that T.BCD and T.ACD.

Best ResponseYou've already chosen the best response.0Since we know that the triangles are congruent, we can say for sure that: \[\angle B \cong \angle A\]

Best ResponseYou've already chosen the best response.0Thank you @Owlcoffee I'm almost positive the answer is B, then.. Seeing how BC=AD. That was the only option in the multiple choice

Best ResponseYou've already chosen the best response.0The answer is not "B". Because BC=AD is given information.
