Description

In this unit pupils learn how to recognise the relationship between the unit circle and the trigonometric ratios of sine, cosine and tangent. Pupils then apply this knowledge to solve trigonometric problems.

Pupils have recently learned about geometrical properties of similarity and the Pythagorean Theorem. This knowledge is further developed to build on their understanding of congruence and similarity with right-angled triangles. In this unit, similarity is used to extend a right-angled triangle in the unit circle to any other right-angled triangle.

  1. Checking and securing understanding of similar triangles
  2. Checking and securing understanding of Pythagoras' theorem
  3. The unit circle
  4. Scaling the right-angled triangle from the unit circle
  5. Sine and cosine ratios
  6. Tangent ratio
  7. Using the sine ratio
  8. Using the cosine ratio
  9. Using the tangent ratio
  10. Choosing the right trigonometric ratio
  11. Choosing an appropriate method for finding lengths of a triangle
  12. Problem solving with trigonometry
