Follow the instructions and try drawing your own constructions using a pencil, ruler, a compass and some paper. Also get to know how loci and three figure bearings can help us in our daily lives.
Follow the instructions and draw the perpendicular through a point on a line construction.
Perpendicular from a point on a line construction
Draw a straight horizontal line and mark a point, P, anywhere on the line.
Placing your compass point on P, draw arcs on both sides of P.
Placing your compass on point A, draw an arc - making sure it is over half way across AB, but above the line.
Without changing the distance between your compass point and pencil, place the compass on point B and do the same - making sure the two arcs cross.
Finally, draw a line connecting points C to the original point P. Line CP is perpendicular to XY.
