[Free Registration/Login may be required to access all resource tools.] Identify intersecting, parallel and perpendicular lines in a plane

This lesson introduces students to Activity Center and is intended to help students interpret whether lines are parallel or perpendicular. [Requires Adobe Reader.]

This activity will help students understand the relationship between the slopes of parallel and perpendicular lines.

Students use Cabri Jr. App to investigate the slopes and equations of parallel and perpendicular lines.

In this activity, students investigate how equations of parallel and perpendicular lines relate to each other. They use the drawing and measurement tools of Cabri Jr. to explore the slopes of lines. [Requires Adobe Reader.]

This site displays formulas and examples, pertaining to slope, for parallel and perpendicular lines.

Describes and gives good examples relating to the slopes of parallel and perpendicular lines.
