Pythagoras and Trigonometry are core topics in secondary maths, but they’re also where many students lose confidence. Memorising formulas, choosing the wrong ratio, or not knowing where to start often leads to frustration and careless mistakes in exams. This Casefile is designed to fix that.
The Pythagoras & Trigonometry Casefile breaks the topic down into clear, manageable steps. Concepts are explained carefully, with each method shown in context so students understand when and why to use it — not just what formula to write down.
Worked examples model good exam technique, and every question is supported by full solutions so students can learn independently without constant help.
Instead of repetitive worksheets, students work through investigative scenarios where trigonometry is used to measure distances, heights, angles, and locations. This helps students see how the maths fits together and reduces the habit of guessing under pressure.
Build confidence with Pythagoras’ Theorem and trigonometric ratios
Recognise which method to use in exam questions
Reduce common mistakes caused by confusion or poor setup
Practise exam-style questions with clear guidance
Work independently without relying on ongoing tutoring
Ideal for students who find trigonometry confusing or overwhelming, as well as those revising for exams and needing a reliable, structured resource. Suitable for GCSE, IGCSE, IB MYP, and high school maths.
This Casefile focuses on understanding, accuracy, and calm problem-solving — the skills that actually lead to better exam results.
These are the topics that are covered within the Case File and each topic has worked examples covering the most common misconceptions
