Deleted Syllabus of Class 10 Maths CBSE 2025-26
The Deleted Syllabus of Class 10 CBSE 2025-26 Maths includes the removal of selected chapters, exercises, or topics as part of CBSE syllabus rationalisation. Students must prepare strictly according to the latest CBSE Class 10 Maths syllabus 2025-26 to avoid studying non-exam content.| CBSE Class 10 Maths Syllabus 2025-26 Deleted Chapters | |
| Chapter | Deleted 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 the division algorithm for polynomials with real coefficients |
| Pair of Linear Equations in Two Variables | Simple problems on equations reducible to linear equations |
| Coordinate Geometry | Area of a Triangle |
| Triangles | Proof of the Theorems: 1. 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 each other. 2. The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides. 3. In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides. 4. In a triangle, if the square on one side is equal to the sum of the squares on the other two sides, the angle opposite to the first side is a right angle. |
| Constructions | Whole Chapter Deleted |
| Trigonometric Identities | Trigonometric ratios of complementary angles |
| Surface Areas and Volumes | Frustum of a cone, problems involving converting one type of metallic solid into another and other mixed problems (problems with a combination of not more than two different solids) |
| Statistics | Step deviation method for finding the mean, cumulative frequency graph |
