GCSE & iGCSE Trigonometry worksheet

Trigonometry worksheet for GCSE and iGCSE maths: SOHCAHTOA, exact values, elevation and depression, sine rule, cosine rule and 3D. With full solutions.

A complete trigonometry worksheet for Pearson Edexcel GCSE (1MA1) and International GCSE (4MA1), written so one resource works for both tiers. Every section is clearly labelled Foundation or Higher, and questions get harder as you go.

What’s covered — Foundation

Using sin, cos and tan to find a side or an angle in a right-angled triangle
Exact values of sin, cos and tan for 0°, 30°, 45°, 60° and 90°
Angles of elevation and depression

What’s covered — Higher (grades 6 to 9)

The sine rule
The cosine rule
Area of a triangle using ½ab sin C
3D trigonometry problems

How it’s structured

A. Worked examples & Your turn — a model solution beside a matching question to try
B. Fluency — core skills
C. Reasoning — explain it
D. Problem solving — unfamiliar, multi-step questions
E. Exam practice — exam-style questions with mark allocations

123 marks across Sections B to E (61 Foundation, 62 Higher), with a progress tracker on the front page so students can record their score per section. The exact values are asked for without a calculator even though the rest of the sheet allows one, matching how both specs examine them.

How to use it

Works as a full lesson, homework, a cover lesson or targeted intervention. Because each tier is labelled, you can set the Foundation sections to one group and the Higher sections to another from the same print.

What’s included

13-page worksheet (PDF, printable, with diagrams and answer spaces)
