This document discusses different types of geometric shapes. A line extends endlessly in both directions and contains countless points. A ray extends endlessly in one direction from an endpoint, while a line segment is a part of a line with two defined endpoints and a measurable length.

3. A line is a straight path which extends
endless in both directions.
A Line can represented not constructed. A
line contains countless points.

4. S
A ray is a part of line
which extends endlessly
in one direction.
It has one end point.

5. A B
A line-segment is a part of line.
It has two end points.
A line-segment can be constructed and
has a definite length which can be
measured.
