Telangana board - Class 9 Mathematics syllabus (2018-19)

Telangana board Class 9 Maths Syllabus is prescribed by the Board of Secondary Education, Telangana popularly known as  BSE, Telangana . The board was established during the year 2014. BSE-Telangana strives hard to establish and nourish secondary education in the state of Telangana.

Syllabus and Textbooks are written and published by the State Council of Educational Research and Training, Telangana in short SCERT. This autonomous body is instrumental in publishing textbooks and syllabus. Topics covered under class 9 mathematics are huge. Here syllabus instructs students and teachers about organising study plan precisely.

Class 9 Mathematics syllabus under Telangana state board comprises of topics like – Number systems, Polynomials, linear equations in two variables, Coordinate geometry, Euclid’s geometry, lines and angles, triangles, quadrilaterals, area, circles, constructions, mensurations, statistics and probability etc.
