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.
