Similarly, you may ask, what is the difference between perpendicular and parallel?
Two lines are said to be parallel when they are equidistant from each other and will never intersect or touch. In simple terms, the slope of two parallel lines is equal. Slope of perpendicular lines, on the other hand, are negative reciprocals of each other meaning the lines cross each other at right angle.
Secondly, which way is perpendicular? Perpendicular lines can face any direction. They can be crossways, up and down, or side-to-side on the page. They do NOT need to be standing straight up from the bottom or side of the page. They just have to be 90° to each other.
Similarly, you may ask, are train tracks parallel or perpendicular?
The ties of a railroad track are perpendicular to the rails and of the same length. This common length is the distance between the rails. (If parallel lines exist, then railroad tracks in space can go on forever.)
How do I know if lines are perpendicular?
Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other. Their product is -1!
