Answer:
You just need to prove ΔAFO and ΔAEO congruent. That way you can show ∠ BAO = ∠ CAO. Thus, OA is the angle bisector of angle A.
Step-by-step explanation:
As OB and OC are angle bisectors,
∠ABO = ∠OBC and ∠ACO = ∠OCB
ΔFOA ≅ ΔEOC by AAA
Therefore ∠FOA = ∠EOA and FO=EO - (i)
Now, in ΔAFO and ΔAEO:
Using, AO = AO and equation (i)
ΔAFO ≅ ΔAEO by SAS
Thus, ∠FAO = ∠EAO
Therefore, OA is the internal angle bisector of ∠A.
