Answer 1

please write in one language

Answer 2

Given :-

• OA = OB
• OD = OC .

To Find :- which of the following is true ?

A) ∆BOC ≅ ∆AOD

B) ∆BOC ≅ ∆DOA

C) ∆OBC ≅ ∆AOD

D) ∆BOC ≅ ∆ADO

Solution :-

in ∆BOC and ∆AOD, we have ,

→ OB = OA (given)

→ OC =OD (given)

→∠BOC = ∠AOD (given)

we know that,

• If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

So,

→ ∆BOC ≅ ∆AOD (By SAS congruence .)

Therefore, Option (A) is True.
