  • Once you know which rule to use, simply label your triangle, substitute in the values and rearrange if necessary

Exam Tip

  • If you are given two angles in a triangle, finding the missing angle by subtracting from 180° might help.
  • Make sure you are careful to pick the correct rule to use, you’ll need to remember all the rules as they aren’t in the formula booklet.
  • Make sure your calculator is in degree mode (D).
  • Always check your answers are sensible…
    • Have I remembered to square root at the end?
    • Have I remembered to use?-1?
  • Check if the question asks you to round your answer.
