This is a complete lesson on proving lines are parallel using vectors that looks at how to use vectors to show the three points are co-linear or that 2 lines are parallel. The lesson is designed with the new GCSE specification in mind.

### Lesson Objective

- To produce geometrical proofs to prove that points are co-linear and that vectors/lines are parallel.

### Who is this Lesson For?

This pack is designed for GCSE higher tier students. It could also be used with high ability Key Stage 3 students.
