Plan mathematics EE modelling, proof, and communication

A student is planning a mathematics EE about "using geometry to compare roof-truss designs for a garden shed" using measurements, diagrams, and load-estimate assumptions. Choose the route that keeps the inquiry mathematical rather than only practical. Select the mathematical focus, mathematical method, communication check, and mathematical limit. Then answer this in your own words: why would this route keep the EE research process focused and authentic? AI will analyse your reasoning, evidence, research judgement, documentation, reflection quality, and expression.
