A worksheet on the trigonometric ratios sine, cosine and tangent. Students will find trigonometric ratios of angles in right-angled triangles given two of their sides. They are required to use the Pythagorean Theorem to find the third side of the triangle and then write the trigonometric numbers.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 finding sine, cosine, and tangent ratios from given right-angled triangles. It provides structured practice that requires students to apply Pythagoras’ theorem first to find missing side lengths before determining the ratios.

Are you searching for a ready-to-print secondary maths resource that combines core right-angled triangle skills? This Trigonometry Ratios and Pythagorean Theorem Worksheet provides high-quality, exam-style practice for Key Stage 4 (KS4), Year 10, and Year 11 pupils working on advanced shape and geometry fluency.

This easy-to-use resource encourages deep mathematical thinking. Each question presents a right-angled triangle with only two sides labeled. Pupils must first independently use Pythagoras’ theorem to find the length of the missing side. Following this step, they must accurately apply SOH CAH TOA frameworks to find the fractional sine, cosine, and tangent ratios for both acute angles.

What Features are Included?

  • Multi-Step Question Set – 6 comprehensive right-angled triangle problems specifically structured to test consecutive knowledge of side calculations and ratio setup.
  • Scaffolded Workspace – Structured answer blocks that seamlessly guide pupils through varied triangle rotations and missing side configurations.
  • Full Solutions Pack – Complete visual answer keys displaying every calculation step (such as IG^2 = 12^2 + 5^2 leading to IG = 13cm) along with the final fraction values for fast marking, peer evaluation, or self-assessment.

Versatile Classroom Applications:

  • Core practice lessons or rigorous revision sessions for GCSE Higher and Foundation tiers
  • Independent desk work or weekly secondary maths homework tasks
  • Pre-exam diagnostic checks to ensure complete retention of right-triangle properties
  • Targeted intervention material for pupils looking to master multi-part geometry questions
    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.
