This is a Word document worksheet involving finding the missing angles using circle theorems for KS4.

A colleague of mine gave me this idea of using records and circle theorems – you have to calculate the missing angles to get the turntable fixed in each case.

I’ve chosen some of my favourite albums! A separate answer sheet is included.
