Question

. ਦਿੱਤੇ ਗਏ ਚਿੱਤਰ ਵਿੱਚ OA=OB ਅਤੇ OD=OCਹੈ ਤਾਂ ਹੇਠ ਲਿਖੀਆਂ ਵਿੱਚੋਂ ਕਿਹੜਾ ਸਹੀ ਹੈ? In the given figure, OA=OB and OD=OC then which of the following is true? दिए ये चित्र में OA=OB तथा OD=OC है तो निम्न में से कौन सा कथन सही है? *

∆BOC ≅ ∆AOD
∆BOC ≅ ∆DOA
∆OBC ≅ ∆AOD
∆BOC ≅ ∆ADO​

Answer 1

Answer:

option A =∆BOC ≅ ∆AOD

is correct 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
