How do you find parallel and perpendicular lines?If two non-vertical lines that are in the same plane has the same slope, then they are said to be parallel. Two parallel lines won't ever intersect. If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular.
What is the difference between parallel and perpendicular lines?Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle. Created by Sal Khan and Monterey Institute for Technology and Education.
How are slopes of parallel lines related?In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.
How do the slopes of perpendicular lines compare?The slopes of parallel lines are equal, and the slopes of perpendicular lines are opposite reciprocals.
