Two triangles are congruent if they have the same 3 sides and the same 3 angles.
Another way to prove that two triangles are congruent is if they have 2 equal sides and the angle between those sides is equal too.
In this case, we have 2 equal sides and equal angles but the angles are not the angles formed by those sides. So, we can't prove that they are congruent.
Answer: The angle B is not the angles formed by sides AB and AC and the angle D is not the angle formed by sides AD and AC.
