It may be useful to look at M5 constructions
Constructions are accurate drawings of shapes using a ruler and protractor. In M6 you may be asked to construct using a pair of compasses, a pencil and a ruler
Definitions of perpendicular, bisector and locus
If two lines are drawn at right angles to each other, they are said to be perpendicular.
A line drawn to cut another line or angle in half is a bisector.
The path of a point that moves according to a certain rule is a locus.
The plural of locus is loci.
Practise these constructions until you can do them without looking at the instructions.
