what is a perpindicular line?a street intersection.. u no?? like in traffic
I think the road is a intersecting lines do you think that is write?
If you are sitting in a room, the ceiling and the floor are parallel to each other. The walls are perpendicular to the floor and to the ceiling. So any line on these surfaces will be parallel to or perpendicular to any line on the other surface. And if they were not, the building could be quite unstable.
Examples of horizontal lines in the real world include the horizon where the sky meets the land or sea, the straight line of a calm lake's surface, the boundary between the wall and floor in a room, and the straight line of a ruler placed flat on a table. Horizontal lines are parallel to the horizon and perpendicular to vertical lines.
Yes, but only if they are exactly vertical and exactly horizontal (90 degrees angular difference). For real-world examples, many vertical lines can be perpendicular to a single "horizontal" curved line at the points of intersection.
As an example without them trains wouldn't be able to operate.
you are th dumbest in the world. there is a dead girl with her eyes and mouth sewn shut waiting for you in ur closet. she will start humming when you get in ur bed tonight and watch you
