The vectors 1 2 3 and 2 4 6 are parallel, but 1 2 3 and 2 4 6 are not parallel. (f) Name a pair of perpendicular lines. Line m is perpendicular to line p since the two lines intersect to make right angles. "The lines intersect and are perpendicular." This is true because the slopes of the two lines are opposite-reciprocals of each other. Discover a geometry definition for both coplanar and non coplanar lines with diagrams and examples. _____4.when two planes intersect, their intersection is a line.
