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.

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.

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).
