Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope: When one line has a slope of m , a perpendicular line has a slope of −1 m

Jan 16, 2024 · The two lines are each vertical. That is, they're both perpendicular to the x-axis and parallel to the y-axis. Any two lines that are each parallel to a third line are parallel to each other.

Answer: Lines with the same slope are parallel and if the slope of one line is the negative reciprocal of the second line, then they are perpendicular. Let's see how to identify parallel and perpendicular lines.
Demonstrates how to determine if slopes are for parallel lines, perpendicular lines, or neither. Explains why graphing is not generally helpful for this type of question.
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y -intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
Learn how to tell if two distinct lines are parallel, perpendicular, or neither. Use the slope formula to calculate the slope of each line to determine if they are parallel, perpendicular, or neither.

Mar 31, 2018 · When two lines (or two sides of a polygon) are parallel, their slopes will be equal. When two lines (or two diagonals of a polygon) are perpendicular, their slopes will be opposite reciprocals of each other. The table below encapsulates this information.
