Right angled triangles

This is an INTERNAL exam worth 3 credits.

Apply right-angled triangles in solving measurement problems, this involves;

  • use trigonometric ratios (sine, cosine, tangent)
  • Pythagoras’ theorem in two and three dimensions
  • recognise when shapes are similar and use proportional reasoning to find an unknown length
  • select and use appropriate metric units for length and area
  • measure at a level of precision appropriate to the task.
