Abstract
Used by mathematicians over two thousand years ago, the compass and straightedge are still used by mathematics students today. The straightedge is similar to the ruler in that the user can draw a straight line with it, but the straightedge is not marked and cannot be used to measure things. Although many different types of compasses exist, your students probably use the modern compass. The characteristic that makes the modern compass special is tension, which allows the opening between the lead and the pointer to be fixed. By fixing the opening, the user can draw a circle of a given radius and copy a line segment.
