Before discussing the deleted syllabus, students must keep a copy of the recent CBSE 10th Maths syllabus 2024-25 to mark the topics which are no longer relevant. Check and download the CBSE 10th Mathematics syllabus 2024-25 PDF from the link provided here.

CBSE Class 10 Maths Deleted Syllabus

CBSE has not introduced any major changes to the latest 2025 Maths Class 10 syllabus. Thus, students can refer to the previous year’s textbooks and other study material freely. To get a clear idea of which topics are no longer covered in the CBSE Class 10 Maths syllabus, check the table below:

Chapter	Topics
REAL NUMBERS	Euclid’s division lemma Decimal representation of rational numbers in terms of terminating/non-terminating recurring decimals.
POLYNOMIALS	Statement and simple problems on division algorithm for polynomials with real coefficients.
PAIR OF LINEAR EQUATIONS IN TWO VARIABLES	Simple problems on equations reducible to linear equations.
QUADRATIC EQUATIONS	No Deletion
ARITHMETIC PROGRESSIONS	No Deletion
COORDINATE GEOMETRY	Area of a triangle
TRIANGLES	Proofs of the following theorems are deleted: 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. The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides. In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides. 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.
CIRCLES	No Deletion
CONSTRUCTIONS	Full Chapter Deleted
INTRODUCTION TO TRIGONOMETRY	No Deletion
TRIGONOMETRIC IDENTITIES	Trigonometric ratios of complementary angles
HEIGHTS AND DISTANCES	No deletion
AREAS RELATED TO CIRCLES	No deletion
SURFACE AREAS AND VOLUMES	Frustum of a cone Problems involving converting one type of metallic solid into another and other mixed problems. (Problems with combination of not more than two different solids be taken).
STATISTICS	Step deviation Method for finding the mean Cumulative Frequency graph
PROBABILITY	No deletion
