1. ) REAL NUMBERS (16 Periods) (*9*)

inch . ) Report on representation of natural numbers, integers, and rational numbers on the number line. Representation of terminating / non-terminating recurring decimals on the number line through consecutive magnification. Rational amounts like recurring/ terminating decimals. Operations on real statistics.

2. ) Cases of non-recurring/non-terminating decimals. Existence of all nonrational amounts (absurd amounts ) such as root23, and also their representation on the line. Explaining that each real number is represented with a exceptional point on the amount and conversely, viz. Every stage on the number line reflects a distinctive actual number.

3. ) Definition of n th root of a true number.

4. ) Rationalization (with accurate significance ) of real amounts of this sort


and (and their combinations) where y and x are all natural number and a and b are integers.

5. ) Remember of legislation of exponents with powers that are essential. Reasonable exponents with favorable real foundations (to be accomplished with particular instances, allowing student to get there at the typical laws)


inch . ) POLYNOMIALS (2-3 Periods)(*9*)

Definition of a polynomial in 1 variable, together with examples and counterexamples. Coefficients of a polynomial, provisions of a polynomial and no polynomial. Amount of a polynomial. Constant, linear, quadratic and cubic polynomials. Monomials, binomials, trinomials. Factors and multiples. Zeros of a polynomial. Motivate and State that the Remaining Theorem using illustrations. Record and evidence of the Factor Theorem. Factorization of ax2 + bx + c), a ≠ 0 in which a, c and b are real numbers, also of cubic polynomials with the Variable Theorem.

Remember of algebraic identities and expressions. Verification of Truth:

and their usage at factorization of polynomials.


Remember of linear equations in 1 variable) Intro into the equation in 2 factors. Focus on terminal equations of the type ax+by+c=0. Describe the linear equation in 2 factors has many solutions and warrant their own being written as pairs of real numbers, restraining them showing they lie online. Graph of linear equations in 2 factors. Cases, issues from true to existence, including issues on Ratio and Proportion as well as algebraic and graphic solutions getting done simultaneously.



Even the Cartesian plane, coordinates of a place, titles and provisions related to the coordinate plane, notations, plotting points from the plane.


inch . ) INTRODUCTION TO EUCLID’S GEOMETRY (maybe not for appraisal ) (6 Periods) (*9*)

Background – Geometry in India along with Euclid’s geometry. Euclid’s way of formalizing detected happening in to strict Communication using definitions, common/obvious ideas, axioms/postulates and theorems. The five postulates of Euclid. Equivalent variants of this fifth postulate. Showing the association between axiom and theorem, such as:

(Axiom) inch. Given two different points, there’s only 1 line .

(Theorem) 2. (Prove) Two different lines may not need more than 1 point in keeping.

2. ) LINES AND ANGLES (1 3 Periods) (*9*)

1. ) (Motivate) When a beam stands onto a point, then a total amount of both adjoining angles formed is 180O and the converse.

2. ) (Prove) When two lines intersect, vertically opposite angles are all equal.

3. ) (Motivate) Effects on corresponding angles, alternate angles, inner angles if a transversal intersects two parallel lines.

4. ) (Motivate) Lines that are parallel to any line are parallel.

5. ) (Prove) The total amount of these angles of a triangle will be 1-800.

6. ) (Motivate) In case a negative of a rectangle is produced, the surface angle formed is equal to the total amount of those two inner angles.

3. ) TRIANGLES (20 Periods) (*9*)

inch . ) (Motivate) 2 triangles are congruent if some 2 sides and the included angle of one triangle is equivalent to some 2 sides and the included angle of one different triangle (SAS Congruence).

2. ) (Prove) 2 triangles are congruent if some 2 angles and the included side of one triangle is equivalent to some two angles and the side of their flip Tri Angle (ASA Congruence).

3. ) (Motivate) 2 triangles are congruent if the 3 sides of a triangle are equal to either side of their flip triangle (SSS Congruence).

4. ) (Motivate) Two right triangles are congruent when the hypotenuse and a side of one triangle are equal (respectively) into the hypotenuse and also a side of one other triangle. (RHS Congruence)

5. ) (Prove) The angles contrary to equal sides of a triangle are equal. 6. (Motivate) The sides contrary to equal angles of a triangle are equal.

7. ) (Motivate) Triangle inequalities compared between’angle and confronting unwanted’ inequalities from triangles.

4. ) QUADRILATERALS (10 Periods)(*9*)

1. ) (Prove) The diagonal divides a parallelogram into two congruent triangles.

2. ) (Motivate) At a parallelogram other sides are equal, and conversely.

3. ) (Motivate) At a parallelogram other angles are all equal, and conversely.

4. ) (Motivate) A quadrilateral is a parallelogram when a couple of its sides is equal and parallel.

5. ) (Motivate) At a parallelogram, the diagonals bisect one another and conversely.

6. ) (Motivate) At a corner, the line segment joining the middle points of any two sides is parallel to the other side and also at 1 / 2 it (propel ) its own converse.

5. ) AREA (7 Periods) (*9*)

Inspection theory of area, remember section of a rectangle. (*9*)

inch . ) (Prove) Parallelograms on precisely the exact same base and between the very same parallels have equal location.

2. ) (Motivate) Triangles to precisely the exact same base (or equal foundations ) and between the very same parallels are equal in space.

6. ) CIRCLES (1-5 Periods)(*9*)

Throughout examples, arrive in definition of group and related concepts-radius, circumference, diameter, chord, arc, and secant, business, segment, subtended angle.

inch . ) (Prove) Equal chords of a ring subtend equal angles in the centre and (motivate) its own converse.

2. ) (Motivate) The vertical from the middle of a circle to a chord bisects the chord and conversely, the line drawn through the middle of a ring into bisect a ring is perpendicular to the chord.

3. ) (Motivate) There’s only 1 circle passing through three specified non-collinear points.

4. ) (Motivate) Equal chords of a ring (or of congruent circles) are equidistant from the centre (or even their various centers) and conversely.

5. ) (Prove) The angle subtended by an arc at the centre is twice the angle subtended by it in any given point about the rest of the section of their ring.

6. ) (Motivate) Angles in precisely the exact same segment of a circle are equal.

7. ) (Motivate) In the event a line segment connecting two things subtends equal angle in two other things lying on precisely the exact same side of this line comprising the segment, then the 4 points lie on a ring.

Surface areas and volumes of cubes, cuboids, spheres (including hemispheres) and right curved cylinders/cones.


inch . ) STATISTICS (1 3 Periods) (*9*)

Introduction to Statistics: Group of data, presentation of data tabular kind, ungrouped / grouped, bar charts, histograms (with varying base spans ), frequency polygons. Mean, median and mode of ungrouped data.

2. ) PROBABILITY (9 Periods)(*9*)

History, Repeated experiments and detected frequency method of probability. Focus is determined by empirical probability. (A great period of time and energy to be committed to groupand to human actions to inspire the concept; the experiments must be derived from real – life situations, also out of cases utilized from the chapter on statistics).
