Lesson
6-5: Parallel and Perpendicular Lines Objectives: (MA.C.2.4.1, MA.C.3.4.2) To determine whether lines are parallel. (MA.C.3.4.2, MA.D.1.4.2) To determine whether lines are perpendicular with different parameters of a graph.
Parallel lines are lines in the same plane that never intersect.
Perpendicular lines are lines that intersect to form right angles.
Small Groups Activity: Modeling Math - Slope of Parallel and Perpendicular Lines
Key Concepts
Slopes of parallel lines
Nonvertical lines are parallel if they have the same slope and different y-intercepts. Any two vertical lines are parallel.
Slopes of perpendicular lines
Two lines are perpendicular if the product of their slopes is -1. A vertical and horizontal line are also perpendicular.
