Which of the following pairs of angle will be equal in the given figure. Given ∠2 = 30∘
∠1= ∠3
∠2 = ∠3
∠1 = ∠4
both (b) and (c)
∠2 = 30∘
By law's of reflection
⇒ ∠2 = ∠3 = 30∘
Also ∠1 + ∠2 = 90∘ (∵ normal)
⇒ ∠1 = 60∘
Similarly ∠4 = 60∘
⇒ ∠2 = ∠3 and also ∠1 = ∠4
Which of the following pairs of angle will be equal in the given figure. Given ∠2=30∘
