  • Zeros of a polynomial
  • Relationship between zeros and coefficients of quadratic polynomials.
  • Statement and simple problems on division algorithm for polynomials with real coefficients.
  • 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.
  • Problems on equations reducible to linear equations.
  • (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.
  • If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.
  • If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
  • If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
  • 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.
  • 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.
  • Trigonometric ratios of an acute angle of a right-angled triangle.
  • Proof of their existence; motivate the ratios, whichever are defined at 0° and 90°.
  • Values (with proofs) of the trigonometric ratios of 30°, 45° and 60°. Relationships between the ratios.
