2. constructions Perpendicular from a Point outside a Line A powerpoint presentation by Carmelo Ellul Head of Department (Mathematics)

3. constructions  AB is the perpendicular to XY.  Centre G and same radius draw another arc.  Centre F and sufficient radius draw an arc.  Label the point of intersection B.  Join AB.  AB  XY.  Centre A and any sufficient radius draw an arc of a circle to cut XY at F and G. From point A construct a line perpendicular to XY. Task: Construction: Perpendicular from a Point outside a Line A XY FG B Conclusion:
