4 self-marking Additional Maths practice questions on Tangents to a circle, written specifically for Cambridge IGCSE Additional Maths (0606) across Single tier. Instant marking with full worked solutions on every question.
Start practising Tangents to a circle (no account needed)A few of the 4 questions, from easier to harder. Choose your exam board and tier to practise them, with every answer marked.
When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.
Gives the distance from an external point to the centre as the tangent length, instead of using Pythagoras to subtract the radius component
Stops before factorising/simplifying an equation into the form needed to explicitly identify a repeated root, leaving the proof incomplete
Uses the origin as a circle's centre instead of the actual given centre when finding a radius gradient or tangent
