Line Segment : A line segment id part of a line. It has two end points.
Ray : A ray is part of a line. It has one end point and goes endlessly on one direction.
Concurrent Lines : Lines that pass through the same point are called concurrent lines.
Collinear Points : If three or more points lie on a straight line, the points are said to be collinear points.
Non -Collinear Points : Three points not lying in the same straight line are called the non – collinear points.
Plane : A plane is a flat surface that goes on endlessly indefinitely in all directions.
