Pass Check: Constructions & Loci
Use compasses and a straight edge accurately; leave all arcs visible.
Locus
A set of points that follow a rule, e.g. equidistant from a point or line.
Perpendicular bisector
A line at 90 degrees through the midpoint of a segment; every point on it is equidistant from the two ends.
Angle bisector
A line that splits an angle into two equal halves; every point on it is equidistant from both arms.
Bearing
A direction measured clockwise from north, always given as three figures, e.g. 065 degrees.
