Solution :-

______________________________________________________________________________

☆ ΔABC, AB = AC ⇒ ∠B = ∠C

[Angles opposite to EQUAL sides are equal]

● Also OA and OB are bisectors of angles B and C.

 1/2angle a = 1/2 angle b

 ⇒ ∠OBC = ∠OCB ∴ OB = OC

☆[Sides opposite to equal angles are equal] 

●Now consider, Δ’s AOB and AOC 

:- OA = OA (Common SIDE)

:-  AB = AC (Given) 

:- OB = OC (Proved) 

:- ΔAOB ≅ ΔAOC [By SSS congruence criterion]

 ⇒ ∠OAB = ∠OAC That is OA is bisector ∠A.
