Code breaker:Circle theorems

Thirteen circles drawn to the true angles, covering all seven theorems: the angle at the centre, the semicircle, the same segment, cyclic quadrilaterals, tangents, the alternate segment and chords. Some need two steps, such as a tangent then an isosceles triangle. One per A4.

A free GCSE geometry and measures puzzle with answers, spec code G10. It goes with the lessons on circle theorems: angle at the centre, circle theorems: angle in a semicircle, circle theorems: angles in the same segment, circle theorems: cyclic quadrilaterals, circle theorems: tangents, circle theorems: alternate segment and circle theorems: chords.
