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.
