Points

Lines intersect in points. The meeting place of two edges is called a point (a vertex). At each of the eight vertices it will be seen that three lines meet. The dot made on paper by a fine pencil point represents a point. No matter how fine the pencil point is, however, the dot is a geometrical solid since it has length, breadth, and thickness, and a point has no length, no breadth, and no thickness. A point indicates but has no size.
