To try to solve a geometric problem without drawing a diagram of the
situation would be rather silly. Yet a drawing can be quite useful
sometimes in solving non-geometric problems. As a matter of fact, there
are times when drawing a diagram to solve a non-geometric problem is
indispensable. Yet determining when a problem can be better solved with
the aid of a diagram is something that comes with some practice. In this
chapter, we will give you a few illustrations to begin your thinking in that
direction. We will look at some problems that make use of a drawing to
clarify a situation, or help the problemsolver reach a satisfactory conclusion
