Topics Covered in Circle and System of Circles

This chapter includes several essential topics for JEE Advanced:

Basic Equation of a Circle

• Standard form: (x – h)² + (y – k)² = r²

• General form: x² + y² + 2gx + 2fy + c = 0

• Relation between standard and general forms

Understanding the equation of a circle is fundamental for all related problems.

Radius and Center of Circle

• Finding center and radius from general equation

• Distance between centers of two circles

• Applications in system of circles

Accurate determination of center and radius is crucial in intersection and tangent problems.

Equation of Circle Passing Through Points

• Circle passing through three points

• Circle with given diameter

• Circle passing through intersection of lines

JEE Advanced often tests multi-step problems involving points and circles.

Tangent and Normal to a Circle

• Equation of tangent at a point on the circle

• Equation of tangent using slope

• Equation of normal

• Angle between tangent and radius

Tangents and normals are frequently tested in JEE Advanced coordinate geometry.

Condition for Tangency

• Tangent from an external point

• Number of tangents from a point to a circle

• Chord of contact

Tangency conditions are essential for solving both direct and applied geometry problems.

System of Circles

• Intersection of two circles

• Coaxial circles

• Radical axis and radical center

• Conditions for orthogonal circles

System of circles problems test conceptual understanding and algebraic manipulation skills.

Length of Chord and Angle Subtended

• Length of chord through a point

• Angle subtended by a chord at center

• Application in solving multiple circle systems

These topics often appear in advanced-level questions in JEE Advanced.

Locus Problems Related to Circles

• Locus of a point satisfying distance conditions

• Circle as a locus

• Interaction with straight lines and other circles

Locus questions enhance logical and analytical reasoning.

Numerical and Conceptual Problems

• Multi-step circle and system of circles problems

• Tangent and intersection combined problems

• Logical reasoning and diagram-based questions

Practicing chapter-wise previous year papers develops problem-solving speed and accuracy.

Diagrams and Visualization
