DETAILS
If the lines intersect, the point of intersection is
.
The equations of the angle bisectors are obtained by solving
.
The slope of the angle bisector in terms of the slope of the two lines
and
is
.
The slope of the perpendicular to the angle bisector is
.
Note that
.
The equation of the angle bisector in point-slope form is
and the equation of the perpendicular to the angle bisector at the point of intersection is
.
