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.
Practise these constructions until you can do them without looking at the instructions.
Follow the instructions and draw this perpendicular bisector of a line segment construction.
Perpendicular bisector construction of a line segment
Begin by drawing a straight horizontal line.
Placing your compass at one end of the line, draw an arc - making sure it is over half way across the line.
Without changing the distance between the pencil and compass point, place your compass at the other end of the line and draw another arc - crossing the first arc in two places.
The points where the arcs cross (A and B) are exactly the same distance from X and Y.
Use your ruler to draw a line connecting the points A and B.
Point M is exactly halfway between X and Y. When drawn correctly, these lines will always be at right angles.
