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.
