M.3-Geometry, trigonometry and vectors

Use areas, volumes, Pythagoras, triangle similarity, trigonometric relationships, vector addition and resolution into perpendicular components in physical contexts.

Use m.3-geometry, trigonometry and vectors to connect the rule to the data and decision in the question.

This matters because m.3-geometry, trigonometry and vectors determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply m.3-geometry, trigonometry and vectors to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: M.3-Geometry, trigonometry and vectors is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
