Mode of Delivery
 This set of materials complements the set of handouts for Chap 1315 (Basic Geometry & Geometrical Construction)
 Part of these lesson materials adopts the flipped classroom approach.
 This means you are required to look at the materials prior to the lesson so that you would have a clearer idea of the focus of the next lesson and be more ready for the discussion and activity.
 You will need to refer to the set of handouts when going through the materials in this Googlesite (materials have been printed and given to you; the softcopy is also available at the end of this page)
Knowledge (Theme/ Topic/ Content) Include:
 Properties of perpendicular bisectors of line segments and angle bisectors
 Construction of perpendicular bisectors and angle bisectors using compasses, ruler, set squares and protractors, where appropriate
At the end of this topic, you should be able to
 construct perpendicular bisectors, angle bisectors and triangles (with varying information given)
 observe the angle properties associated with parallel lines
