SINGLE PLOT DRAWINGS

Single plot drawings are shapes that can be drawn with a single line—that is, you do not lose contact between the pencil and paper, and you do not trace the same line twice. Try to trace the following shapes using the single plot method.

EXAMPLE

These types of problems are studied in the branch of mathematics known as graph theory. Graph theory is actually used by engineers, biologists, psychologists, physicists, and urban planners as part of their profession.
