IB Math AI SL 3.3 – Applications of Right and Non-Right-Angled Trigonometry

This editable slide-deck focuses on practical and exam-relevant applications of trigonometry, including both right-angled and non-right-angled triangles. Students will be guided through solving problems involving 2D and 3D contexts, calculating side lengths and angles using the sine rule, cosine rule, and area formula for any triangle.

The resource also covers angles of elevation and depression, compass bearings, and constructing clear, labelled diagrams from descriptive statements. Realistic examples (such as a helicopter hovering above a lake or a landscape path across a park) link abstract trigonometric methods to real-world contexts.

Aligned with the IB Math AI SL Topic 3.3 syllabus—the “Applications of right and non-right-angled trigonometry” section—this deck supports classroom teaching, targeted revision and independent study.
