Slopes and Parallel and Perpendicular Lines
Slopes and Parallel and Perpendicular Lines

In this video, you will explore parallel and perpendicular lines. There are special characteristics which make lines parallel or perpendicular. Parallel lines have the same slope. Lines that are parallel will extend forever and never intersect. Perpendicular lines do intersect and form 90° angles at the point of intersection. This happens because perpendicular lines have slopes that are opposite reciprocals. Click the player button to begin.
