Meanwhile, find details of the deleted portion of the UBSE Class 9 Maths Syllabus 2021-22 from below:

UNIT I : NUMBER SYSTEMS

1. REAL NUMBERS

Representation of terminating / non-terminating recurring decimals, on the number

line through successive magnification.

Explaining that every real number is represented by a unique point on the number

line and conversely, every point on the number line represents a unique real number.

UNIT II : ALGEBRA

1. POLYNOMIALS

State and motivate the Remainder Theorem with examples. Statement and proof of

the Factor Theorem. Identities of the type x3+ y3+ z3— 3xyz = (x + y + z) (x2+ y2+ z2— xy — yz — zx) and their use in factorisation of polynomials.

2. LINEAR EQUATIONS IN TWO VARIABLES

Including problems on Ratio and Proportion

UNIT IV : GEOMETRY

1. INTRODUCTION TO EUCLID’S GEOMETRY

History – Euclid and geometry in India. Euclid’s method of formalizing observed

phenomenon into rigorous mathematics with definitions, common/obvious notions,

axioms/postulates and theorems. The five postulates of Euclid. Equivalent versions of

the fifth postulate. Showing the relationship between axiom and theorem.

1. Given two distinct points, there exists one and only one line through them.

2. (Prove) two distinct lines cannot have more than one point in common.

3. TRIANGLES

1. (Prove) Two triangles are congruent if any two angles and the included side

of one triangle is equal to any two angles and the included side of the other

triangle (ASA Congruence).

2. (Motivate) Triangle inequalities and relation between ‘angle and facing side’

inequalities in triangles.

5. AREA

Review concept of area, recall area of a rectangle.

3. (Prove) Parallelograms on the same base and between the same parallels

have the same area.

4. (Motivate) Triangles on the same base and between the same parallels are

equal in area and its converse.

6. CIRCLES

1) (Motivate) There is one and only one circle passing through three given noncollinear

points.

2) (Motivate) If a line segment joining two points subtendes equal angle at two

other points lying on the same side of the line containing the segment, the

four points lie on a circle.

7. CONSTRUCTIONS

1. Construction of a triangle of given perimeter and base angles.

UNIT V : MENSURATION

1. AREAS

Area of a triangle using Hero’s formula (without proof) and its application in finding
