Summary: Circle Geometry Proofs
The typed pdf documents includes all the examinable circle geometry proofs for the Grade 12 national examination (South Africa). The proofs included are: Theorem 1a & 1b (line drawn from circle centre) ; Theorem 2 (angle at centre and circumference); Theorem 5 (opposite angles cyclic quad) and Theorem 9 (tangent chord theorem).
The summary has been carefully put together. For example, Theorem 2 can appear in three formats and the proof will need to be adjusted according to the given diagram. This summary includes the different proofs.
Each examinable proof has a picture of the theorem, what the theorem is in words, the construction needed (shown in colour) and a simplified proof. It is the perfect summary needed for studying circle geometry proofs in a simplified way. This summary is perfect for Grade 11 & 12 learners, teachers, student teachers, education students or someone studying a course who requires circle geometry.
Each proof clearly sets out what is given, what you are required to prove and what construction needs to be made. The document is typed in Times New Roman for easy reading and the diagrams have been drawn on the computer and they are very neat and legible.
