What is a line? Geometrically, it connects two points. A line is a path traced by a moving point, i.e. a pencil point or a paintbrush. We see lines all around us. Line is a vital element of any artwork.
Actual and Implied lines.
Actual lines
Actual lines are marks or objects that are real lines; they exist physically. Examples of actual lines include lines painted on a highway, tree branches, lines incised on the surface of gravestone, telephone poles, neon signs, and words on a page. Contour lines define the edges of objects, like the sides of a bookcase, the edges of a table, a boulder, a window. Contour lines define both the edges of the object and the negative space between them, such as the space between the rungs of a ladder.
Implied lines
Implied lines are lines that we see in our mind’s eye that fill in the spaces between objects, such as a line of lights in the ceiling and the rows of windows in a large office building. Implied lines are also found in the gaze between two people. We imagine a line that goes from one person’s eyes to the other. Implied lines can also extend beyond the edges of an artwork.

This a good example of implied line: the horizontal stone on top of the vertical stones appears to extend across the vertical stones on either side of it.
Geometric and Organic Lines
Geometric lines
Geometric lines are mathematically determined. They have regularity and hard or sharp edges. True geometric lines are rarely found in nature, but often found in man-made constructions. They convey a sense of order, conformity, and reliability.
