| Key Learning Objectives
|
- Pythagoras' Theorem:
- Identify the hypoteneuse of a right-angled triangle.
- Recall Pythagoras' Theorem.
- Use Pythagoras' Theorem to find the length of any side of a right-angled triangle.
- Further work with Pythagoras' Theorem:
- Pick out right-angled triangles from diagrams (e.g. circles, isosceles triangles).
- Use Pythagoras' theorem to solve problems such as bearins, areas of triangles, diagonals of rectangles etc.
- Sine, Cosine, Tangent:
- Use the SIN, COS and TAN keys on a calculator.
- Identify the sides of the right-angled triangle as hypoteneuse, adjacent and opposite.
- Recall the ratios for sin, cos and tan, perhaps using SOHCAHTOA mnemonic.
- Finding Lengths in Right-Angled Triangles:
- Use the appropriate ratio.
- Finding Angles in Right-Angled Triangles:
- Use the appropriate ratio to find angles.
- Mixed Problems with Trigonometry:
- Find angles of elevation and depression.
- Apply trigonometric rations and Pythagoras's theorem to solve assorted problems, including bearings.
