  I was assuming you were talking about flat triangles (since you didn't
specifically mention smooth triangles and their vertex normals...)

  Naturally if you have a smooth triangle and one of the vertex normals
points to the wrong direction, the lighting in between will be wrong,
as the in-between normals are interpolated.
