Circle Theorems - Higher Level Only
Subjects / Maths / Shape, Space and Measures
This title begins by revising circle definitions, including the terms radius, chord and segment. It then looks at various theorems. These are facts about the angles created in circles when certain lines meet. For example, did you know that when a tangent and a radius meet, they do so at an angle of 90 degrees? We also look at proving certain theorems. Once you've listened to the proof of a theorem, have a go at proving it yourself. It will help you to remember the theorem if you practice doing this.
It would be useful if you revised circles, angles and Pythagoras' theorem before listening. Please note that it is essential for you to view the supporting images in this title, due to the difficult concepts they explain.
