MCQ
If two lines intersect each other then:
- ✓Vertically opposite angles are equal.
- BCorresponding angles are equal.
- CCo-interior angles are equal.
- DAlternate interior angles are equal.
✓
Answer
Correct option: A.
Vertically opposite angles are equal.
$\angle\text{A}+\angle\text{B}=180 ($Linear Pair$)$
$\angle\text{B}+\angle\text{C}=180 ($Linear Pair$)$
On equating ablove equations, we get
$\angle\text{A}+\angle\text{B}=\angle\text{B}+\angle\text{C}$
$\angle\text{A}=\angle\text{C}$
Similarly, $\angle\text{B}=\angle\text{D}.$
