Answer 1

Question-

In the figure shown below, if ∠1 = 60°, find ∠2, ∠3 and ∠4

Answer-

∠1 = ∠2 (Vertically opposite angles are equal)

⇒ ∠2  = 60°

∠1 + ∠3 = 180° (Sum of linear pairs of angles always results to 180°)

⇒ ∠3 + 60° = 180°

⇒ ∠3 = 180° - 60°

⇒ ∠3 = 120°

∠3 = ∠4 (Vertically opposite angles are equal)

⇒ ∠4 = 120°

∠1 = 60°

∠2 = 60°

∠3 = 120°

∠4 = 120°
