MCQ
In $\triangle\text{ABC, }\angle\text{C}=\angle\text{A},$ $BC = 4\ cm$ and $AC = 5\ cm$. then, $AB =?$
- ✓$4\ cm$
- B$5\ cm$
- C$8\ cm$
- D$2.5\ cm$
✓
Answer
Correct option: A.
$4\ cm$
In $\triangle\text{ABC,}$
$\angle\text{C}=\angle\text{A}$
$\Rightarrow\text{AB = BC}$ (sides opposite to equal angles are equal)
$\Rightarrow\text{AB = 4cm}$
$\angle\text{C}=\angle\text{A}$
$\Rightarrow\text{AB = BC}$ (sides opposite to equal angles are equal)
$\Rightarrow\text{AB = 4cm}$
