In this lesson I solve problems involving parallel & perpendicular lines. The lesson is directed towards Cambridge AS Level maths students but could also be useful to higher/extended IGCSE/GCSE students. In question 1 00:52 , I show how to prove whether or not points are collinear (i.e on the same straight line), in question 2 04:13 , we have to find unknown values of k and are told that points are collinear and in question 3 08:48 , we have to prove that two lines are perpendicular to each other.
