Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Positions of a Line with Respect to a Circle, 2. Theorem 10.1: Tangent is Perpendicular to Radius, 3. Number of Tangents from a Point.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 133 questions available for this chapter.

Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Circles after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • A tangent intersects a circle at exactly one point.
  • A secant intersects a circle at two points.
  • A non-intersecting line has no common point with the circle.
  • Tangent at the point of contact is perpendicular to the radius.
  • OP is the shortest distance from the centre to the tangent line.
  • If a point on a tangent lies inside the circle, the line becomes a secant.
  • Inside the circle: no tangent.
  • On the circle: exactly one tangent.
  • Outside the circle: exactly two tangents.

Common Mistakes to Avoid

A tangent can pass through a point inside the circle.

A point on the circle has two tangents.

A point outside the circle has only one tangent.

Memory Tips

Tangent as a limiting secant

Point of contact

Theorem 10.1: Tangent is perpendicular to radius at point of contact
