Years 9&10: Measurement and Geometry

This strand introduces trigonometry and applies measurement skills to complex 3D objects.

Measurement: Calculating the surface area and volume of more complex objects, including cylinders, pyramids, cones, and spheres, as well as composite shapes.

Pythagoras' Theorem: Applying the theorem in 2D and 3D contexts to find unknown lengths.

Trigonometry: This is a major focus. It starts with establishing the basic ratios (SOH CAH TOA) to find unknown sides and angles in right-angled triangles. It then extends to non-right-angled triangles using the Sine and Cosine Rules.

Geometric Reasoning: Proving and applying properties of similar triangles and other geometric shapes to solve problems.
