    if you have normals of A and B pointing to one direction, then blue line direction will be (n(A) + n(B))/2
    who is this? a word of friendly advice: FFS stop using AS2

    How I can determine normals direction relative one another?

    On the 2nd thought, you can also do this with direction vectors themselves. Assuming you know some two points on A and B, you have d(A) = (A - O)/|A - O| and d(B) = (B - O)/|B - O|, then d(C) = (d(A) + d(B)) / |d(A) + d(B)|

    I dont understand mean the d(C) - what is it?
