A broken line is composed of two or more straight lines at angles to
each other (see fig. 19). To draw them begin (saying) _one_, make a
point; _two_ a point below at the left; _three_, a point above at the
left; _four_, draw a line from the left hand point to the lower point;
at the word _five_, from the lower point to the upper right hand point.
For practice draw numerous lines in the same way, keeping them parallel
to each other, as shown in fig. 20.

[Illustration: Fig. 25.]
In example, fig. 21, the arrangement of the points is changed--let the
student draw at the words, as follows: _One_, a point; _two_, a point
above at the left; _three_, a point below at the left; _four_, draw from
the point at the left to the upper point; _five_, from the upper point
to the lower right hand point; continue to add parallel lines to
complete the figure as shown.
Figs. 22 and 23 are given as examples to practice, making first the
points and then the connecting lines and afterward the parallel lines to
complete the figures.
