National curriculum code and descriptions (partially) covered by the layers.

know the formulae for:

  • Pythagoras’ theorem, a 2 + b2 = c 2 ,
  • the trigonometric ratios,
    • sinθ = opposite /hypotenuse ,
    • cosθ = adjacent/hypotenuse and
    • tanθ = opposite /adjacent ;
  • apply them to find angles and lengths in right-angled triangles and, where possible, general triangles in two and three dimensional figures

know the exact values of sinθ and cosθ for θ = 0o , 30o , 45o , 60o and 90o ;

know the exact value of tanθ for θ = 0o , 30o , 45o and 60o 

know and apply the sine rule,  and cosine rule,  to find unknown lengths and angles

know and apply Area = 1/2 absinC to calculate the area, sides or angles of any triangle
