  • Trigonometry and Pythagoras
    • Finding out Pythagorean triples
    • Pythagoras in 3D shapes= applying your knowledge and proofs
    • Naming your right angled triangles, labeling them properly
    • Ratio of angles in similar triangles
    • working with trigonometric formulae to either find Hypotenuse, Adjacent or Opposite. Tip use; (soh,cah,toa)
    • Finding the angle (theta) by use the negative reciprocal of Sin, Cos and Tan after formulae used
    • Using your exact values of Sin, Cos and Tan at 0°, 30°, 45°, 60° and 90°
    • From a whole triangle, cutting it and using your 30° and 60° Sin, Cos and Tan Ratios for angles.
    • The sine Rule and problems solving with it's formula
    • The cosine rule to find unknown sides
    • The area rule to find the area of triangles trigonometrically.
    • Angles of elevation and depression
