Question :- In given figure, which is pair of vertically opposite angles ?दिए गए चित्र में, कौन सा शीर्ष सन्मुख कोणों का जोड़ा है ?

Answer :-

vertically opposite angles :-

• Here , vertical means they share the same vertex.
• When two lines intersect each other, then the opposite angles, formed due to intersection are called vertically opposite angles.
• vertically opposite angles are always equal.

From image now, we can see that,

→ ∠1 and ∠4 share same vertex and between two intersecting lines .

Therefore,

→ ∠1 and ∠4 are vertically opposite angles . (also equal.)

Also, we can see that,

→ ∠5 and sum of ∠2 and ∠3 share same vertex and between two intersecting lines .

Therefore,

→ ∠5 and (∠2 + ∠3) are vertically opposite angles . (also equal.)

Hence, (∠1 , ∠4) and (∠5 , (∠2 + ∠3)) are pairs of vertically opposite angles.
