BROKEN LINES.
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].

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.
