.5 a half is a half no matter what it is half of
Half of '33' is 16.5 Half of '34' is 17 The half-way point ( mid-point ) between the two numbers is 33.5
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).
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
