Triangle Types and Angles – GCSE Maths Worksheets (Unit 4.1D)
Description:
This differentiated pack focuses on the classification of triangles by their side and angle properties. Students also learn how to apply angle facts in problems involving different triangle types.
Each level comes with a matching answer sheet to help students reflect on and improve their understanding.
Included Levels:- Red: Identify triangle types from side lengths or angles
- Amber: Solve for unknown angles using properties of isosceles and right-angled triangles
- Green: Multi-step angle problems involving mixed triangle rules and justifications
- Classify triangles (equilateral, isosceles, scalene, right-angled)
- Understand and apply internal angle properties
- Use triangle reasoning in unfamiliar diagrams
- Foundation GCSE Maths – Edexcel, AQA, OCR
- Intervention groups, homework, or assessment practice
