CBSE Class 10 Maths Chapter 10 Circles Syllabus 2026–27

CBSE Class 10th Chapter Circles focuses on properties of circles, especially tangents and their relationships with radii. It deals with understanding how lines interact with a circle and how these relationships are used in solving geometry problems.

CBSE Class 10 Maths Chapter 10

The Circles chapter concentrates on the geometric properties related to tangents drawn to a circle. Instead of covering the entire geometry of circles, it specifically looks at how tangents behave and what rules they follow.

You will study how a tangent touches a circle at exactly one point and how it is always perpendicular to the radius at the point of contact. Another key area covered here is the relationship between tangents drawn from a single external point. Questions in the board exam involve using these results to prove relationships or calculate lengths based on given conditions.

What Will You Learn in Circles?

In Chapter 10 Circles, you will focus on:

  • Understanding the definition of a tangent and the point of contact in a circle

  • Identifying the relationship between radius and tangent at the point of contact

  • Learning key theorems related to tangents drawn from external points

  • Applying these theorems to solve geometry-based problems

  • Interpreting diagrams correctly to identify given relationships

  • Solving proof-based and numerical questions involving tangents

CBSE Class 10 Circles Topics: Detailed Breakdown

Here’s a quick look at the chapter components that help in covering every concept properly:

Topic

Description

Tangent to a Circle

A line that touches the circle at exactly one point. 

Point of Contact

The exact point where the tangent touches the circle. 

Tangent–Radius Theorem

States that the radius at the point of contact is perpendicular to the tangent. 

Length of Tangents

Explains that tangents drawn from an external point to a circle are equal in length. 

Number of Tangents

Describes how many tangents can be drawn from a point inside, on, or outside the circle. 

Important Topics in Chapter 10 Circles

For effective revision, give priority to:

  • Understanding and applying the tangent–radius perpendicular property in different situations

  • Using the theorem of equal tangents from an external point in problem-solving

  • Solving proof-based questions where logical steps must be clearly shown

  • Interpreting diagrams accurately to identify given and required elements

  • Practising standard questions to build familiarity with common patterns

To ensure alignment with the latest CBSE guidelines and optimise your preparation, it is recommended to review the updated list of deleted topics for Class 10 Maths and focus only on the currently prescribed syllabus.

Class 10 Chapter 10 Circles FAQs

1. What is a tangent to a circle in Class 10 Maths?

A tangent is a line that touches the circle at exactly one point, known as the point of contact.

2. Why is the radius perpendicular to the tangent?

According to the tangent–radius theorem, the radius drawn to the point of contact is always at a right angle to the tangent.

3. How to find the length of tangents from an external point?

Tangents drawn from the same external point to a circle are equal in length, so you can use this property to form equations.

4. How many tangents can be drawn to a circle from a point?

From a point outside the circle, two tangents can be drawn; from a point on the circle, one; and from inside, none.
