See the attached image below for statements and reasons.
Why is this correct?
The congruence between angles B and D is established due to the fact that it is given. Additionally, the parallelism between segments AD and BC is also given.
By applying the reflexive property, we can affirm that segment AC is congruent to itself (segment AC) in statement 3, considering AC as a transversal.
Finally, statement 4 is derived from the Angle-Angle-Side postulate, which identifies two congruent angles and one congruent side in the given context.
