Construct Perpendicular from On-Line Point: RulerCompass 3
This applet walks through the ruler and compass construction of a line perpendicular to a given line through a given point C, on the line.
Drag the Steps slider to see the steps of the construction. The construction assumes that the user has already worked through the construction of the perpendicular bisector of a line segment.
