Answer 1

Answer:

Given,

In the fig,

∠BOA= ∠BAO

and ∠COD= ∠CDO

RTP:-

AB || CD

PROOF:-

In the fig,

∠BOA=∠COD [ vertically opposite angles]

............(i)

Now,

∠BOA= ∠BAO

=> ∠BAO= ∠COD [ From (i) ]

=> ∠BAO= ∠CDO [∠COD= ∠CDO]

But,

∠BAO and ∠CDO are alternate angles with respect to transversal AD and line segment AB and CD

Therefore,

AB || CD.

Hence Proved.
