The key subtopics in Circles are: Tangent to a circle – definition & properties, Number of tangents from a point – zero, one, two cases, Theorem: tangent perpendicular to radius at point of contact, Theorem: lengths of tangents from external point are equal, Tangent-chord angle (alternate segment theorem). Focus on these for CLASS 9 preparation.
Based on past paper analysis, Circles typically has 1-2 questions in CLASS 9. Weightage: Medium.
Circles questions are typically Numerical format. Expect calculation-based problems requiring formula application.
