Lesson 2: Transversals - Transversals Definitions
Constructing Knowledge
In this section, you will discover how a line crossing two parallel lines creates angles with special relationships. The diagram of the lacrosse stick shows the frame and mesh as a series of lines and angles. The construction of the stick and mesh helps players catch and control the ball. Notice that the mesh is actually a series of parallel lines (and transversals) made of tightly stretched nylon.
A line that crosses two other lines is called a transversal. If the lines that the transversal crosses are parallel, some special relationships exist.

|
This transversal crosses parallel lines. There are relationships between the angles in this diagram. |
|
This transversal crosses lines that are not parallel. The angles formed do not have any special relationships. |
In this lesson, you must make sure that the transversal crosses lines that are parallel. If the transversal does not cross parallel lines, the relationships do not exist.
