If two lines intersect, then the vertically opposite angles are equal. Let lines A B and C D intersect at O. We have to prove ∠A O D=∠B O C and ∠A O C=∠B O D Proof: Since, ray O A stands on line C D. ⇒ ∠A O C ∠A O D=180^∘ Again since, ray O C stands on line A B ∠A O C ∠B O C=180^∘ From (i) and (ii) ⇒ ∠A O C ∠A O D =∠A O C ∠B O C ∠A O D =∠B O C Similarly, we can prove ∠A O C=∠B O D. figure cant copy | Numerade
