Ray Ray is a line that extends in both direction infinitely and so it does not have any fixed point.
Extended Line Extended Line is a line that is fixed at one point and extends infinitely on other end.
Vertical Line Vertical Line extends infinitely in both direction but it is always vertical.
Horizontal Line Horizontal Line extends infinitely in both direction but it is always horizontal.
Parallel Lines Parallel Lines are bunch of parallel Trend Lines.
