In the given figure, AB∥CD, ΔAOB and ΔDOC are isosceles triangles
∠ABO is 32∘, then ∠BOD is
64∘
Given that ∠ABO is 32∘
∠BAO=32∘ (Since ΔAOB is isosceles)
∠AOB cannot be 32∘ because ∠AOB must be an obtuse angle
Then ∠AOB=180∘−(32∘+32∘)=180∘−64∘=116∘
∠COD=116∘, (Opposite angles)
∠BOC=180∘
∠BOD+∠COD=180∘
∠BOD=180∘−116∘=64∘ (Opposite angles are equal)
