a half-line with a designated end point which extends in only one direction without stopping
This is called a ray.
The line, itself, is a subset (though not a proper subset). A ray is a subset of a line with one end-point which extends in only one direction. A line segment is a subset of a line with two end points. A point is a subset of a line.
A ray can be described as the half line with designated end point which extends in only one direction without stopping.
end point
yes. only one
a half-line with a designated end point which extends in only one direction without stopping
No as it has only one end point.
The radius
It is a ray.
You have given the definition of a ray.
This is called a ray.
only two points are required to form a line .One is the starting point and other is the end point
The line, itself, is a subset (though not a proper subset). A ray is a subset of a line with one end-point which extends in only one direction. A line segment is a subset of a line with two end points. A point is a subset of a line.
One-point perspective has only one vanishing point.
Ray.
No point is the beginning of a line or both, the beg. and end. edge is only the end at the tippy tip.
