Unit I: Number Systems

1. Real Numbers

  • Euclid’s division lemma
  • Fundamental Theorem of Arithmetic – statements after reviewing work done earlier and after illustrating and motivating through examples
  • Proofs of results – irrationality of √2, √3, √5, decimal expansions of rational numbers in terms of terminating/non-terminating recurring decimals

Unit II: Algebra

1. Polynomials

  • Zeros of a polynomial
  • Relationship between zeros and coefficients of quadratic polynomials
  • Statement and simple problems on division algorithm for polynomials with real coefficients

2. Pair of Linear Equations in Two Variables

  • Pair of linear equations in two variables and their graphical solution
  • Geometric representation of different possibilities of solutions/inconsistency
  • Algebraic conditions for number of solutions
  • Solution of a pair of linear equations in two variables algebraically – by substitution, by elimination and by cross multiplication method
  • Simple situational problems must be included
  • Simple problems on equations reducible to linear equations

Unit III: Geometry

1. Triangles

  • Definitions, examples, counter examples of similar triangles
  • (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
  • (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side
  • (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar
  • (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar
  • (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
  • (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
  • (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares on their corresponding sides
  • (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides
  • (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 triangle

Unit IV: Trigonometry

1. Introduction to Trigonometry

  • Trigonometric ratios of an acute angle of a right-angled triangle
  • Proof of their existence (well defined); motivate the ratios, whichever are defined at 0o and 90o
  • Values (with proofs) of the trigonometric ratios of 30o, 45o and 60o
  • Relationships between the ratios

2. Trigonometric Identities
