In the given figure, ∠ABC = ∠ABD, BC = BD. Then, ∆CAB is congruent to:

Explanation

To prove the congruence of triangles △CAB and △DAB , let's examine the given information: ∠ABC = ∠ABD BC = BD AB is a common side in both triangles △CAB and △DAB . With these conditions, we can apply the **SAS (Side-Angle-Side) Congruence** criterion: The side AB is common to both triangles. The angles ∠ABC and ∠ABD are equal. The sides BC and BD are equal. By SAS, △CAB ≅ △DAB . Answer: The correct answer is DAB.
