About This Lesson
The 23rd in Mr Barton's Autograph Video tutorial series. In a jam-packed edition of Mr Barton's Autograph Videos we look at all things to do with Tangents, including the Two Tangents Theorem. This also leads us to discover a slick way of marking the intersection of two lines on Autograph and how to measure the length of line segments. 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.
Another interesting use of autograph, great for those wanting to use the programme more frequently
