Expert Answer:

let ABC  be an iso triangle with AB=AC

so angles B and C are equal.

Let the bisectors of angles B , C meet at O (say)

in triangles OBC, OCB,

we have

1/2[angle B]=1/2[angle C]... since B=C given

so

OBC=OCB

so

OB=OC...sides opp to equal angles are equal)

so bisectors are equal.
