Description

This video looks at the amazing properties of parallel lines and a single transversal (a line which passes through two other lines). I look at how the angles which are created can be identified and found using the FUZX rules! Which, in real Maths speak would otherwise be known as, Vertically Opposite Angles, Cointerior Angles, Corresponding Angles and Alternate Angles. Phew! Such long words! There are lots of worked examples all explained in an easy to understand way
