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 theContinue reading

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 atContinue reading

This week we look at our third Circle Theorem – the classic Angles in the Same Segment Theorem. There is also a quick demonstration of how to set up a nice looking label for points,Continue reading

This week we look at our second Circle Theorem – this classic Cyclic Quadrialteral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms…

Whilst we are on a roll with the Angle at the Centre Theorem, why not have a quick look at a nice little twist? We can use Autograph to set up some circumstances where theContinue reading

This week we take a look at how to construct Circle Theorems using Autograph, beginning with the Angle at the Centre Theorem. We also see how understanding this theorem leads us to another theorem forContinue reading

This week we take a look at how to construct Circle Theorems using Autograph, specifically the angle at the centre theorem. There is also a brief look at tangents, all of which should arm youContinue reading
