Rays/Angle bisector/Definition

For two linearly independent vectors ${\displaystyle {}v}$ and ${\displaystyle {}w}$ in a normed real vector space ${\displaystyle {}V}$, the line generated by

${\displaystyle {\frac {v}{\Vert {v}\Vert }}+{\frac {w}{\Vert {w}\Vert }}}$

is called the angle bisector of the two vectors.
