Why this why now
This is an advanced unit investigating more complex properties of circles, and as such requires in depth knowledge and understanding of shapes, shape properties, proof, angles and ratios.
Prior knowledge requirements
- Identify parts of a circle (radius, diameter, chord, tangent)
- Recognise angle facts in triangles and quadrilaterals
- Apply geometric reasoning and proof techniques
