  • Chapter 10

    Chapter Objective:

    * Line segments can go up and down, from side to side, and in every direction.


    Perpendicular line segments - Line segments that meet at right angles.

    Drawing triangle - This instrument is used to draw perpendicular and parallel line segments.

    Parallel line segments - Parallel line segments are parts of lines that are ALWAYS the same distance apart.

    Base - This is the straightedge of a drawing triangle; the side of the drawing triangle.
