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.
Something went wrong, please try again later.
I think the worksheet for the perpendicular bisector through a point is missing for slides 12-16?
Exactly what I needed, saved me a lot of time. Thank you!
Fantastic resource! Thanks!!
Excellent resource. Absolutely love the animated compass to demonstrate constructions. Thanks!
Excellent as always
