6.6 Parallel and Perpendicular Lines - Jon Blakely
Parallel and Perpendicular Lines Now that we have talked about Lines in general, we want to talk about a couple of ways that Lines can interact with each other. The most important thing you need to know about Parallel and Perpendicular Lines is that the relationship between Parallel Lines is a relationship between the slope of the Lines , and the same goes for Perpendicular Lines . Slopes of Parallel Lines Two Lines are Parallel if and only if they have the exact same slope. For example if the slope of one of the Lines is -2, then the slope of the other one has to be -2. This property is fairly easy to understand why it is true. Remember that the slope of a line represents the steepness of the line . So, if two Lines are Parallel , they would have to have the same steepness, otherwise they would eventually intersect, making them no longer Parallel by definition.
The most important thing you need to know about parallel and perpendicular lines is that the relationship between parallel lines is a relationship between the slope of the lines, and the same goes for perpendicular lines.
