.5 a half is a half no matter what it is half of
Since a half dozen is six, it means the each side or direction is equal to the other.
a half-line with a designated end point which extends in only one direction without stopping
A ray can be described as the half line with designated end point which extends in only one direction without stopping.

Ray.
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
You have given the definition of a ray.
This is called a "ray". (It is equal to one half of a line.)
The set of points on a straight curve that extends to infinity in both directions is a line. A ray is the set of points that lie on a straight curve that is terminated at a point, and continues to infinity. It is also called a half-line. If the set is terminated at a point at both ends, then it is a line segment.
No. A half line (also called a ray) is a linear object which starts at the first point, and extends to infinity through the second point. So the half-line (or ray) AB starts at point A, and shoots 'through' B and continues past B to infinity. The half-line BA is the other way around: it starts at point B, and then shoots 'through' A and continues past A to infinity. These two half-lines/rays end up extending to infinity in opposite directions, so they are not the same (not congruent).
Of course it changes. For example, at some point it is moving in one direction; half a cycle later it is moving in the opposite direction.
