Constructing perpendicular and angle bisectors

A FULL LESSON on constructing perpendicular and angle bisectors.

Assumed prior knowledge:

  • Use of a compass and straight edge
  • Measuring an angle

We are learning about: Constructing bisections
We are learning to: Construct a perpendicular bisector and an angle bisector

Differentiated objectives:

  • Developing learners will be able to construct the perpendicular bisector of a straight line.
  • Secure learners will be able to construct the perpendicular bisector of a straight line from a point.
  • Excelling learners will be able to construct perpendicular bisectors and angle bisectors.

Starter: MWB activity inspired by schoolyourself.org.
Main: Worked through problem with visual prompts and steps followed by practice questions on worksheets. Answers to first three parts of each of the non-worded questions are given on the PPT.
