A line segment is a part of a line that is bounded by two distinct end points and contains every point on the line between its end points. Depending on how the line segment is defined, either of the two end points may or may not be part of the line segment.
An introduction to geometry. A point in geometry is a location. It has no size i.e. no width, no length and no depth. A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points. A line is defined by two points and is written as shown below with an arrowhead. $$\\ \overset{\leftrightarrow}{AB } \\$$ Two lines that meet in a point are called intersecting lines. A part of a line that has defined endpoints is called a line segment. A line segment as the segment between A and B above is written as:
