Constructing argument from circle diagram
This means building a correct geometric conclusion from the marks and labels in a circle figure.
Practice This ConceptMain explanation
Teacher explanation
A good circle answer starts with observation. You identify tangents, radii, equal lengths, and right angles from the diagram, then connect them using the correct theorem. Many students know the facts but do not know how to organise them into a proper argument. This concept trains that skill.
Example
From a diagram, if OA and OB are radii to tangent points A and B, you can argue OA ⟂ tangent at A and OB ⟂ tangent at B.
Simple analogy
Mark it, match it, prove it.
Common confusion
Students often write conclusions before giving the reason chain from the diagram.
Exam tip
Read the diagram like a proof: mark, identify, then conclude.
