SDL (04) Geometrical Construction



Mode of Delivery
  • This set of materials complements the set of handouts for Chap 13-15 (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
