Question

if two straight lines ab and CD cross at the point o. Experimentally verify that angle AOC =Angle BOD​

Answer 1

Answer:

∠BOD = ∠AOC

(Vertically opposite angles are equal)

∠BOD = 50°

(ii) ∠AOD

∠AOD + ∠BOD = 180°

∠AOD + 50° = 180° (From i)

∠AOD = 180° - 50°

∠AOD = 130°

(iii) ∠BOC = ∠AOD

(Vertically opposite angles are equal)

∠BOC = 130°
