Help your students prepare for their Maths GCSE with this free circle theorems worksheet of 44 questions and answers
Circle theorems are a set of angle properties that apply within circles. We can use the circle theorems to work out missing angles.
To access circle theorems we need to be confident with the names of the key parts of a circle including the centre of the circle, the diameter of the circle, the radius of the circle, a tangent to the circle, a segment of the circle, a sector of the circle and a chord within the circle.
We also need to be confident at labelling angles using three letter notation. For example, angle BCD is the angle created at C when travelling from B to C to D. The centre of a circle is often labelled O, in which case the angle BOD would be the angle at the centre O when travelling from B to O to D.
The circle theorems are:
Looking forward, students can then progress to additional circle theorems, and other geometry worksheets, for example an angles in polygons worksheet or area and circumference of a circle worksheet.
For more teaching and learning support on Geometry our GCSE maths lessons provide step by step support for all GCSE maths concepts.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
