List of all circle theorems
Web4.3 PROOF OF THEOREMS All SEVEN theorems listed in the CAPS document must be proved. However, there are four theorems whose proofs are examinable (according to the Examination Guidelines 2014) in grade 12. In this guide, only FOUR examinable theorems are proved. These four theorems are written in bold. 1. WebDrag the statements proving the theorem into the correct order. The angle at the centre of a circle is twice the angle at the circumference. Similarly ∠AOC = 180° – 2 x ∠OCA. OB = OC (radii of circle) ∠BOA = 2∠BCA Q.E.D. Construct radius OC. ∠COB = 180° – 2 x ∠BCO (Angle sum of triangle OBC) To prove: ∠BOA = 2∠BCA.
