Lines and Midpoints
A pdf file of lines and midpoints
Lines go on for ever. A line segment is what we normally draw on a piece of paper and it has two end points.
Line segments have a midpoint and various other points can be calculated along their length using ratio and mean averages.
When drawing line segments, it is important that you apply the pressure to the ruler as this is the thing that is likely to slip and spoil your diagram.
