Construction of Parallel Lines

Mike May
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.
