Circle Theorems
What are circle theorems?
- Circle Theorems deal with angle facts that occur when lines are drawn within, or connected to, a circle
- These can be used in conjunction with the other angle facts you have learned, to solve geometry problems and find missing angles
- To solve some problems you may need to use the angle facts you are already familiar with from triangles, polygons, and parallel lines
- You may also have to use the formulae for circumference and area
What do I need to know about circles?
- You must be familiar with the names of parts of a circle including radius, diameter, arc, sector, chord, segment and tangent
