Class 9 can be called the foundation of higher classes and, therefore, the content of Class 9 Mathematics emphasises the in-depth understanding of concepts. Concepts like coordinate geometry, Heron’s formula, Euclid’s geometry and statistics are introduced in this grade while concepts like number system, triangles, areas and construction are extensions to the parts studied in earlier grades.
