standard fayre - nice to have answers and also solutions but all of this is available in word format using past exam paper software.

Have not worked through the answers but a very good set of problems, with workings - what more could you ask for. I always tell my students how to find the centre of a circle using the perpendicular bisectors from a pair of chords- just a suggestion maybe for a further question!

A great help, thank you. I seem to have a different answer for Q14c(ii). Should it be 20 degrees rather than 70 degrees as it's an isosceles triangle so 180 - 140 = 40 degrees, shared equally between the two other angles?
