Pythagoras

• Use Pythagoras’ theorem in 2D and 3D.
  • Understand, recall and use Pythagoras’ theorem in 2D, then in 3D problems.
  • Understand the language of planes, and recognise the diagonals of cuboid.
  • Calculate the length of a diagonal of a cuboid.

Trigonometry

• Use the trigonometric ratios and the sine and cosine rules to solve 2D and 3D problems.
  • Use the trigonometric ratios to solve 2D and 3D problems.
  • Understand, recall and use trigonometric relationships in right-angled triangles, and use these to solve problems in 2D and in 3D configurations.
    • Find the angle between a line and a plane (but not the angle between two planes or between two skew lines),
    • Find angles of elevation and angles of depression.
  • Use the sine and cosine rules to solves 2D and 3D problems.
