I’m pleased to read that exercise #1 has been helpful to you. If you go to #13 onwards you will be able to double check your work against the answers I have given. Good luck with your GCSEs :-)

My Year 10s loved this - thanks! Took me about 45 mins of thinking to get all answers and reasons:<br />
a=31(angle at centre is x2 angle at circumference),<br />
b=152 (kite/tangent)<br />
c=76, (2 radii make an isosceles) <br />
d=64 (angle in semi-circle)<br />
e=60 ( opposite angles in cyclic quad)<br />
f=90 (half of 180)<br />
g=62 ( alternate angles)<br />
h = i=72 (create isosceles triangle, tangent is perpendicular=90, alternate angles)

I love to read this sort of feedback! Thank you. <br />

I think I started to get a better grip of these pile ups from #5 onwards, but I never found a way of giving the answers without displaying them in preview on this site - until #14. You can read a bit more about it here...<br />

I couldn’t find my original printouts, and my inkjet cartridges are empty, so I had to sketch it out again to check your answers! Full marks :-)<br />

A challenging activity for students aiming for high grades.<br />
Would be even better if answers were provided. Here are mine:<br />
a = 31, b = 152, c = 76, d = 64, e = 50, f = 90, g = 62, h=72. i = 72.
