History – Geometry in India and Euclid’s geometry. Euclid’s method of formalizing observed phenomenon 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) 1. Given two distinct points, there exists one and only one line through them. (Theorem) 2. (Prove) Two distinct lines cannot have more than one point in common.

1. LINES AND ANGLES (15) Periods
2. (Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180O and the
3. (Prove) If two lines intersect, vertically opposite angles are
4. (Motivate) Lines which are parallel to a given line are
5. TRIANGLES (22) Periods
1. (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).
2. (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).
3. (Motivate) Two triangles are congruent if the three sides of one triangle are equal to three sides of the other triangle (SSS Congruence).
4. (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 (RHS Congruence)
5. (Prove) The angles opposite to equal sides of a triangle are
6. (Motivate) The sides opposite to equal angles of a triangle are

1. (Prove) The diagonal divides a parallelogram into two congruent
2. (Motivate) In a parallelogram opposite sides are equal, and
3. (Motivate) In a parallelogram opposite angles are equal, and
4. (Motivate) A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and
5. (Motivate) In a parallelogram, the diagonals bisect each other and
6. (Motivate) In a triangle, the line segment joining the mid points of any two sides is parallel to the third side and in half of it and (motivate) its converse.
1. CIRCLES (17) Periods

1.(Prove) Equal chords of a circle subtend equal angles at the center and (motivate) its converse.

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

1. (Motivate) Equal chords of a circle (or of congruent circles) are equidistant from the center (or their respective centers) and conversely.

4.(Prove) The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle.

5.(Motivate) Angles in the same segment of a circle are equal.

6.(Motivate) If a line segment joining two points subtends equal angle at two other points lying on the same side of the line containing the segment, the four points lie on a circle.
