Division, Continued
Preferred
method for
dividing lines
into
proportional
parts
To divide a line into proportional parts, use this table:
Step
Action
1
Given line AB, draw a perpendicular line at B.
2
Select any scale and set the first increment (0) at A.
3
Position the scale so that the total number of increments aligns with
the perpendicular line at B.
4
Set off the desired increments with tiny pencil marks. In this case
2, 3, and 4 units are marked.
5
Draw vertical lines through these points to the given line.
