    CBSE Class 10 Mathematics Syllabus 2018-2019

    CBSE has released the Class 10 syllabus for the academic session 2018-2019. In this article you will get the complete syllabus of CBSE Class 10 Mathematics.

    This syllabus is according to the assessment structure that was introduced in class 10 from the last academic session. Under this assessment scheme the board examinations were made mandatory for all students of CBSE Class 10. Now students are assessed on the basis of a final exam in all scholastic subjects which carries 100 marks with an 80 marks component for class 10 Board examination and a 20 marks component for Internal Assessment (IA). IA comprises Periodic Tests (PT) with weightage of 10 marks, Notebook Submission of 5 marks and Subject Enrichment Activities of 5 marks. Students must know the entire syllabus before starting preparing for the exams.

    In the CBSE Class 10 syllabus 2018-2019, you will find:

    • Topics to be studied during the complete course
    • Weightage allotted to each unit
    • Question paper design for the board examination
    • Components of Internal Assessment
    • Prescribed books

    Find below the complete syllabus for CBSE Class 10 Mathematics:

    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, by completing the square 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)

    Motivation for studying Arithmetic Progression Derivation of the nth term and sum of the first n terms of an A.P. and their application in solving daily life problems.


    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.
