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