Division
Introduction
When you want two unequal portions or more than two equal portions of a
line, you are dividing not bisecting. One of the most frequently executed
geometric constructions is dividing a line into multiple equal or proportional
parts.

Action
Given line AB, draw a perpendicular line (BC).
Place a scale or ruler with the first increment (0) at A.
Place the desired increment on the scale at the termination point of
the perpendicular line (BC).
Make tiny pencil marks indicating the desired measurements along
the scale.
Draw vertical construction lines perpendicular to the given line and
parallel to each other. This divides the line into multiple equal
increments.
Figure 2-20 shows the steps for the preferred method of dividing a line into
multiple equal increments.
