CBSE Class 10 Mathematics Syllabus 2020-2021

CBSE Class 10 Maths Syllabus for the new academic session 2020-2021, has been released. Students must check this new syllabus while starting with new chapters. Like this year, Board Exam 2021 will again offer two versions of Mathematics paper to students, one easy and other of the standard level. However, the syllabus for both types of papers remains common. So, all students are advised to refer to the latest syllabus while they prepare for their school and board examinations.

Contents of CBSE Class 10 Maths syllabus 2020-2021 are:

  • Unit-wise weightage
  • Topics and sub-topics to be prepared from each unit
  • Question paper design for the annual board examination
  • Components of Internal Assessment
  • Prescribed books

CBSE had introduced certain changes in the Maths question paper structure in the board exam 2020. About 25% of the questions in the paper were of objective type with each carrying 1 mark. The same is expected to be followed in the next year's board examinations. For this, you can check the question paper design suggested by CBSE in this new syllabus.

2. Pair of Linear Equations in Two Variables (15 Periods)

Pair of linear equations in two variables and graphical method of their solution, consistency/inconsistency.

Algebraic conditions for number of solutions. Solution of a pair of linear equations in two variables algebraically - by substitution, by elimination and by cross multiplication method. Simple situational problems. Simple problems on equations reducible to linear equations.

3. Quadratic Equations (15 Periods)

Standard form of a quadratic equation ax2 + bx + c = 0, (a ≠ 0). Solutions of quadratic equations (only real roots) by factorization, and by using quadratic formula. Relationship between discriminant and nature of roots.

Situational problems based on quadratic equations related to day to day activities to be incorporated.

4. Arithmetic Progressions (8 Periods)

1. Lines (In two-dimensions) (14 Periods)

Review: Concepts of coordinate geometry, graphs of linear equations. Distance formula. Section formula (internal division). Area of a triangle.


1. Triangles (15 Periods)

Definitions, examples, counter examples of similar triangles.

1. (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.

3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.

4. (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.

5. (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.

6. (Motivate) If a perpendicular is drawn from the vertex of the right angle of a right triangle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other.

7. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.

8. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

9. (Prove) In a triangle, if the square on one side is equal to sum of the squares on the other two sides, the angles opposite to the first side is a right angle.

2. Circles (8 Periods)

 Tangent to a circle at, point of contact.

1. (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.

2. (Prove) The lengths of tangents drawn from an external point to a circle are equal.

3. Constructions (8 Periods)

1. Division of a line segment in a given ratio (internally).

2. Tangents to a circle from a point outside it.

3. Construction of a triangle similar to a given triangle.


1. Introduction to Trigonometry (10 Periods)

1. Areas Related to Circles (12 Periods)

 Motivate the area of a circle; area of sectors and segments of a circle. Problems based on areas and perimeter / circumference of the above said plane figures. (In calculating area of segment of a circle, problems should be restricted to central angle of 60°, 90° and 120° only. Plane figures involving triangles, simple quadrilaterals and circle should be taken.)
