Answer 1

Answer:

option i is correct

Step-by-step explanation:

pls mark me as brainliast and thanks to my all answer

Answer 2

Given : OA=OB तथा OD=OC

To Find : which of the following is true

∆BOC ≅ ∆AOD

∆BOC ≅ ∆DOA

∆OBC ≅ ∆AOD

∆BOC ≅ ∆ADO​

Solution:

OA = OB

∠AOD = ∠BOC

OD = OC

=>∆ BOC ≅ ∆AOD  SAS  rule

∆BOC ≅ ∆AOD  is correct

check others

∆BOC ≅ ∆DOA

=>   OC = OA      but OC = OD

Hence does not satisfy

∆OBC ≅ ∆AOD

=> BC = OD   but   OD = OC

Hence does not satisfy

∆BOC ≅ ∆ADO​

=> BO  = AD     but  OB = OA

Hence does not satisfy

∆BOC ≅ ∆AOD  is correct
