(as shown in Fig. 30)
(2) Is AD = BC ? Why?
(u) Is DC = AB ? Why?
(im) Is CA = AC ? Why?
(iv) Is A ABC = A ADC ? Why?

Answer 1

Answer:

So, AD ∣∣ BC

∴ ∠DAC = ∠ACB  --- ( Alternate angle)

∴ ∠ACB = 32degree  

 

∠AOB + ∠BOC = 180 degree  

  --- (straight angle)

⇒70 degree  

 + ∠BOC = 180 degree  

 

∴ ∠BOC = 110 degree  

 

In △BOC,

∠OBC + ∠BOC + ∠OCB = 180 degree  

 

⇒∠OBC  + 110 degree + 32 degree  

 

 = 180 degree  

 

⇒ ∠OBC = 38 degree  

 

∴  ∠DBC = 38 degree
