Free trigonometry quick reference sheet

Free one-page quick reference for right-angled trigonometry: SOHCAHTOA, side definitions, worked side and angle examples, an angle-of-elevation reminder and calculator checks. Keep it for homework support and revision.

Designed for Years 10–11 (ages 14–16) learners who have already met the basic ratios. Covers right-angled triangles and acute angles, with degree-mode calculator instructions. The three compact worked examples show a missing leg, a missing hypotenuse and an inverse trig calculation. An eye-height diagram explains total height on level ground.

Included: matching colour and printer-friendly PDF and editable Word editions. Four files contain the same one-page reference, not four unique pages. No separate questions or answer key are needed; the worked examples are on the sheet.

Free companion to the paid OpenLatitude Right-Angled Trigonometry teaching pack. Use independently; no purchase required. The paid resource provides the full teaching sequence, classroom practice, separate homework and teacher guidance. The SOHCAHTOA exercise sheet with worked answers is another separate free companion.

Print on A4 or choose fit-to-page for another paper size. PDF preserves the layout; Word or compatible software is needed to edit the DOCX. Diagrams are embedded images and are not to scale.
