Study Notes
Understanding Parallel and Perpendicular Lines
- Parallel Lines: Two or more lines that lie in the same plane and never intersect, no matter how far they are extended.
- Relationship between Parallel and Perpendicular Lines: Parallel lines are never perpendicular, and perpendicular lines are never parallel.
Perpendicular Lines
- Perpendicular Lines: Two lines that intersect at a 90-degree angle (right angle).
- Properties of Perpendicular Lines: The slopes of two perpendicular lines are negative reciprocals of each other (m1 = -1/m2).
