equations (only real roots) by factorization, and by using quadratic formula. Relationship
between discriminant and nature of roots.

incorporated.

4. ARITHMETIC PROGRESSIONS (8) Periods

Motivation for studying Arithmetic Progression Derivation of the nth term and sum of the
first n terms of A.P. and their application in solving daily life problems.

 

UNIT III: COORDINATE GEOMETRY

1. LINES (In two-dimensions) (14) Periods

Review: Concepts of coordinate geometry, graphs of linear equations. Distance formula.
Section formula (internal division). Area of a triangle.

 

UNIT IV: GEOMETRY

1. TRIANGLES (15) Periods

Definitions, examples, counter examples of similar triangles.

  1. (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two
    sides in distinct points, the other two sides are divided in the same ratio.
  2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel
    to the third side.
  3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding
    sides are proportional and the triangles are similar.
  4. (Motivate) If the corresponding sides of two triangles are proportional, their
    corresponding angles are equal and the two triangles are similar.
  5. (Motivate) If one angle of a triangle is equal to one angle of another triangle and the
    sides including these angles are proportional, the two triangles are similar.
  6. (Motivate) If a perpendicular is drawn from the vertex of the right angle of a right
    triangle to the hypotenuse, the triangles on each side of the perpendicular are similar to
    the whole triangle and to each other.
  7. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares
    of their corresponding sides.
  8. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the
    squares on the other two sides.
  9. (Prove) In a triangle, if the square on one side is equal to sum of the squares on the
    other two sides, the angles opposite to the first side is a right angle.

 

2. CIRCLES (8) Periods
