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
