Science > Mathematics > Coordinate Geometry > Straight Lines > Condition for Parallelism and Perpendicularity In this article, we shall study the Condition for parallelism and the condition of perpendicularity of lines. Condition for Parallelism: If two lines are parallel, then their slopes are equal. Let slopes of the two parallel lines be m1 and […]
