A worksheet on the trigonometric ratios sine, cosine, and tangent. Students will find trigonometric ratios of acute angles in right-angled triangles where all three side lengths are given.Help your students master the foundational concepts of trigonometry with this ready-to-print practice worksheet! Designed for clarity and skill building, this resource guides students through identifying and writing sine, cosine, and tangent ratios from given right-angled triangles. It provides structured practice that requires students to locate the opposite side, adjacent side, and hypotenuse relative to different acute angles.

Are you searching for a ready-to-print secondary maths resource dedicated entirely to constructing trigonometric fractions? This Finding Trig Ratios Worksheet provides focused, isolated practice for Key Stage 4 (KS4), Year 9, and Year 10 pupils mastering the initial steps of right-angled trigonometry.
This easy-to-use resource strips away complex calculation steps so pupils can focus completely on the core skill of ratio construction. Across 6 comprehensive questions, all three side measurements are fully given. Pupils are required to identify the correct opposite, adjacent, and hypotenuse positions to write the exact fraction ratios for the sine, cosine, and tangent of both acute angles.
What Features are Included?

  • Targeted Question Set – 6 multi-part right-angled triangles specifically structured to practice fraction setup without the distraction of calculating missing side lengths.
  • Scaffolded Layout – Organized answer blocks that accommodate varied triangle rotations, ensuring pupils truly understand angle-to-side relationships.
  • Full Solutions Pack – Complete visual answer keys showing the exact, unsimplified and simplified fractional ratios (such as sin D = 5/13 and tan F = 12/5) for fast marking, peer correction, or self-assessment.

Versatile Classroom Applications:

  • Core introductory lessons for GCSE foundation and higher tiers
  • Focused independent desk work or weekly secondary maths homework tasks
  • Pre-unit diagnostic checks before moving on to solving missing side boundaries
  • Small-group intervention tasks for pupils struggling with formula configurations

UK National Curriculum & GCSE Framework Alignment:

  • Geometry and Measures (G20): Know the formulae for sine, cosine and tangent of an angle and apply them to find unknown lengths and angles in right-angled triangles.If you need any adjustments, let me know.
