The 19th in Mr Barton's Autograph Video tutorial series. This week we look at our second Circle Theorem - this classic Cyclic Quadrilateral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms... 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.

A video tutorial from the Autograph team on conic sections. A step by step guide on how to create a plane and a cone in Autograph and investigate the intersections. Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. The Binomial approximation is often used for approximating powers of numbers close to 1, but how close to 1 do we need to be in order for the approximation to be any good? Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on the feature of 'export to webpage'. Share your work with people who don&'t have Autograph installed using the Autograph player . Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. If you use Autograph with a projector or inteactive whiteboard then it is best to use Whiteboard Mode. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on Euler's 9 Point Circle. In this starter activity for KS3/KS4 you will be introduced to Object Selection and the Right-click Menu, which are used in most Autograph files. Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. Autograph can be used to great effect to enhance a lesson, but to do this you need to follow the simple three step rule. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on vectors. Addition, subtraction and multiplication of vectors in Autograph. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on transformations in 3D. Because of the extra dimension transformations are somewhat different in three-dimensions. In this activity we will see what those differences are. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on how to transform shapes in a graph. Using Autograph to demonstrate different types of transformation: translation, enlargement, rotation and reflection. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team on Sound Mirrors. Very useful whn teaching algebra. In the 1920s, some very large structures were built along the South Coast of England to deal with the increasing threat of aerial attack. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team. We are going to investigate the vector equations of a line x = a + kb and a plane y = a + kb + µc. Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. There may be some occasions when you want to prepare a file in advance of the lesson. For example Pin Boards are great for geometrical reasoning but the construction is not very helpful. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team. A step-by-step guide on how to explore the connection between the angle at the centre of a circle and the angle at any point on the circumference in Autograph. Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team. The concepts learnt in the investigation of areas can also be applied to volumes of revolution. Suppose the region under the curve y = f(x) between x = a and x = b is revolved around the x-axis to form a solid. What is the volume of this solid? How can we approximate the volume?

A tutorial video from the Autograph team. Investigating the exponential function by considering the function y = a^x and its derivative. Clicking on the web-link below takes you to all the videos in this series. Ideal to be used for C2 or C3.

A tutorial video from the Autograph team. A simple visual introduction to differentiation in calculus. Ideal for teaching C1. Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. How can we find the area A under the curve y = f(x) between x = a and x = b? Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. We begin by plotting the sine curve and its gradient function in degrees and use this to motivate the introduction of radians. Clicking on the web-link below takes you to all the videos in this series.
