It is called a line so I don't see why the question arises!
Ray which cross vertical line is called horizental ray.... as simply u can see the gray line is vertical of my text
A line
For any line, there needs to be two points. If the line passes through points and extends in both directions forever, it's a line. If the line just goes between the two points, its called a line segment. If the line goes through both points but only extends in one direction, it's a ray.

A part of a line that extends in one direction with one endpoint is called a ray.
The line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins is called the normal line.

None of the following sets would.

It is called a bisector.
No. Line CD is the same as line DC, but rays are always named from the origin point, so ray DC is a ray pointing in the opposite direction from ray CD.
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
