Circle Theorems – Cyclic Quadrilaterals

By the end of this unit, students will be able to:

1. understand and apply circle theorems to find missing angles in cyclic quadrilateral.

Curriculum Alignment: Key Stage 4: Geometry and measures

• Identify and apply circle definitions and properties, including: centre, radius, chord, diameter, circumference, tangent, arc, sector and segment
• {apply and prove the standard circle theorems concerning angles, radii, tangents and chords, and use them to prove related results}
