MCQ
In fig, if $AD = BC$ and $\angle\text{BAD} = \angle\text{ABC},$ then $\angle\text{ACB}$ is equal to: 
- ✓$\angle\text{BDA}$
- B$\angle\text{BAC}$
- C$\angle\text{ABD}$
- D$\angle\text{BAD}$
✓
Answer
Correct option: A.
$\angle\text{BDA}$
The two triangles are congruent according to ($SAS \ CONGRUENCY$) as $AD = BC$ (given), $\angle\text{BAD} = \angle\text{ABC},$ (given) and $AB = AB$ (common) and hence corresponding angles are equal (cpct).
