A KS4 PowerPoint resource that can be used to introduce and practise concepts around finding the tangent to a circle. The 'warmup' activity assumes knowledge of:
- equation of a circle
- gradients of parallel and perpendicular lines
- finding the equation of a line
- solving simultaneous equations.
The PowerPoint then focuses on combining these to find the equation of a tangent to a circle. There are three worksheets (resource 107541) that work very well alongside the PowerPoint and are differentiated with red (full support), amber (some support)
and green (no support) tasks.
