Circle Theorems (A) WORKSHEET DESCRIPTION
This worksheet will help learners practise using the circle theorems “angles in the same segment are equal” and “the angle at the centre is twice the angle at the circumference”. It may also lead them into some of the other circle theorems.
Section A provides some straightforward diagrams with missing angles to find.
Section B then increases the complexity of the diagrams and changes the type of angle notation used. Follow on from this worksheet with Circle Theorems (B).
