Coplanar – points and lines in the same plane.
Collinear – points that lie on the same line.
Line segment or segment – is part of a line consisting of two
endpoints.
A
B
AB or BA
The measure of AB is written as AB.
Ray – part of a line consisting of one
endpoint and extending indefinitely
in one direction.

Transversal – a line that intersects two or
more coplanar line at two different points.
In the diagram to the right line t is the
transversal.
