However, unlike pieces of paper, planes have no edges. A bug could crawl along a plane forever without falling off. Here is a picture of part of a plane. It has been colored green to make it easier to see. Point A point is one place in space.
Points are really zero- dimensional.
Of course, we can't draw something that has no dimensions. You can imagine that the real point is in the exact center of the dot. The two axes divide the plane into four quarters. These quarters are called quadrants. They are numbered from one to four, starting in the upper right-hand corner and moving counterclockwise.
