LO To assess your understanding of Pythagoras’ Theorem and Trigonometry RAG Key Words: Sine, Tangent, Cosine, Inverse10-Jun-15 Starter Activity Complete the ‘Heard the Word Grid.’ Are there any key words that you have learnt or have a better understanding of now than you did at the start of this unit of work?

Grade DCBA/A* Pythagoras’ Theorem and Trigonometry I can find the length of the hypotenuse in a right angled triangle using Pythagoras Theorem. I can label the Opposite and Adjacent sides to any given angle. I can find the length of a shorter side in a right angled triangle using Pythagoras Theorem. I can choose which trig ratio to apply to a given problem (Sin, Cos, Tan). I can recognise the difference between problems involving right-angled triangles that require Pythagoras’ theorem, or Trigonometry, to be applied. I can find missing lengths and distances in shapes other than right angled triangles using Pythagoras Theorem. I can use trigonometry (Sin, Cos, Tan) to find a missing angle find one of the shorter sides find the hypotenuse. I can calculate the area of a triangle using ½ ab sin C. I can solve 3D Pythagoras problems. I can use the sine and cosine rules to solve 2-D and 3-D problems.

Grade D For each of the triangles below label the sides adjacent, opposite and hypotenuse.

Grade C For each of the triangles above decide which of the Trigonometric Ratios you would use to find the missing side or angle. Grade C Describe the difference between a problem that can be solved using trigonometry and a problem that can be solved using Pythagoras’ Theorem.
