Yes, I'm familiar with Class 9 CBSE NCERT Maths. The NCERT Class 9 Maths textbook covers a range of topics essential for building a strong foundation in mathematics. Here are the key chapters included in the Class 9 syllabus:

1. **Number Systems**: Real numbers, rational and irrational numbers, and their properties.
2. **Polynomials**: Degree of polynomials, zeros of polynomials, and factorization.
3. **Coordinate Geometry**: Introduction to the Cartesian plane, plotting points, and distance formula.
4. **Linear Equations in Two Variables**: Solutions of linear equations and graphical representations.
5. **Introduction to Euclid's Geometry**: Definitions, axioms, and postulates.
6. **Lines and Angles**: Types of angles, pairs of angles, and properties of lines.
7. **Triangles**: Congruence, properties of triangles, and criteria for triangle similarity.
8. **Quadrilaterals**: Properties and types of quadrilaterals.
9. **Areas of Parallelograms and Triangles**: Calculating areas using formulas.
10. **Circles**: Definitions, properties, and theorems related to circles.
11. **Constructions**: Construction of bisectors and triangles.
12. **Heron's Formula**: Finding the area of a triangle when all sides are known.
13. **Surface Areas and Volumes**: Surface areas and volumes of solids like cubes, cuboids, and spheres.
14. **Statistics**: Data representation, mean, median, and mode.
15. **Probability**: Basic concepts of probability.

These chapters help students develop a solid understanding of algebra, geometry, trigonometry, and data handling.
