Perpendicular lines are those that form a right angle at the point at which they intersect. Parallel lines, though in the same plane, never intersect....
What Are Perpendicular Lines?
In mathematics, a line is an infinitely long one-dimensional object. It has no start or end, continuing on forever without ever changing direction. More colloquially, a "line" is any straight object, even if it does have an end point. The relationship...
