About This Lesson
The 22nd in Mr Barton's Autograph Video tutorial series. This week we look at our fourth Circle Theorem - the notoriously difficult Alternate Segment Theorem. Can Autograph help us understand when this theorem works and when it doesn't? There is also a look at how to construct tangents and a sneaky way of measuring angles. Below the video you will find an option to download it and play it on a larger screen, or by clicking on the web-link you can see all the videos in this series
