Explaining that every real number is represented by a unique point on the number line and, conversely, viz., every point on the number line represents a unique real number.
- Definition of nth root of a real number.
- Rationalisation (with precise meaning) of real numbers of the type (and their combinations) where x and y are natural numbers and a and b are integers.

Recall algebraic expressions and identities. Verification of identities:

**2. Linear Equations in Two Variables (16 Periods)**

- Recall linear equations in one variable. Introduction to the equation in two variables. Focus on linear equations of the type ax + by + c=0. Explain that a linear equation in two variables has infinitely many solutions and justify their being written as ordered pairs of real numbers, plotting them and showing that they lie on a line.

**Unit III: Coordinate Geometry Coordinate Geometry (7 Periods)**

The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations.

**Unit IV: Geometry**

**1. Introduction to Euclid’s Geometry (7 Periods)**

History – Geometry in India and Euclid’s geometry. Euclid’s method of formalizing observed phenomena into rigorous Mathematics with definitions, common/obvious notions, axioms/postulates and theorems. The five postulates of Euclid. Showing the relationship between axiom and theorem, for example: (Axiom)

- Given two distinct points, there exists one and only one line through them. (Theorem)
- (Prove) Two distinct lines cannot have more than one point in common.

**2. Lines And Angles (15 Periods)**

- (Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180O and the converse.
- (Prove) If two lines intersect, vertically opposite angles are equal.
- (Motivate) Lines which are parallel to a given line are parallel.

- (Motivate) Two triangles are congruent if any two sides and the included angle of one triangle is equal to any two sides and the included angle of the other triangle (SAS Congruence).
- (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).
- (Motivate) Two triangles are congruent if the three sides of one triangle are equal to three sides of the other triangle (SSS Congruence).
- (Motivate) Two right triangles are congruent if the hypotenuse and a side of one triangle are equal (respectively) to the hypotenuse and a side of the other triangle. (RHS Congruence)
- (Prove) The angles opposite to equal sides of a triangle are equal.
- (Motivate) The sides opposite to equal angles of a triangle are equal.
