Use this worksheet prior to some of our Loci worksheets.
Section A contains line segments that require a perpendicular bisector.
Section B then extends this skill by providing circles with two chords. The centres of these circles can be found by finding where the perpendicular bisectors of the chords intersect.
Section C has three angles to bisect, which is then extended on in section D.
An extension exercise requires perpendiculars from points to lines to be constructed.
