Lines. A ray is a line that originates from a point till infinity.
Step-by-step explanation:
A ray is a form of a line, but it has a starting point. It starts from a point, and extends till infinity in a given or required direction.
This property distinguish completely a ray from a line or segment. Lines extends to infinity in both its directions. And a segment is the length of a line between its starting point and end point.
Thus, we can say that rays are special forms or types of lines.
