Construct a Perpendicular Line through a point Not on the line

Follow these steps to construct a perpendicular line through a point not on the line
1) Using the POINT TOOL, mark point D on segment AB. [br]2) Using the COMPASS TOOL, create a circle with radius CD and center C.[br]3) Using the POINT TOOL, mark point F at the intersection of circle C and segment AB.[br]Next we will create the perpendicular bisector of segment DF. Follow the steps to create below if you don't remember how to construct it.[br]4) Using the COMPASS TOOL, create a circle with radius FD and center F.[br]5) Using the COMPASS TOOL, create a circle with radius FD and center D. [br]6) Using the LINE TOOL, draw a line that passes through C and the intersections of circles F and D.
