Construction of Parallel Lines
This applet walks through the ruler and compass construction of a line
through a given point C, parallel to a given line AB.<br>
Drag the Steps slider to see the steps of the construction. The
construction assumes that the user has already worked through the
construction of a line perpendicular to a given line.
The two points, A and B, which
define the line, and the given point C, can be moved to
new positions by dragging.
