Naming, Measuring and Drawing Angles Lesson | KS3 Geometry | Using a Protractor and Angle Notation

This engaging KS3 geometry lesson teaches students how to correctly name, measure and draw angles using standard mathematical notation, rulers and protractors.

The lesson begins with a retrieval starter on symmetry before introducing clear explanations of how to label lengths and angles using point notation (for example AB and ∠DAB). Students then practise measuring given angles accurately, followed by step-by-step guidance on how to draw angles to specific measurements using a protractor.

The lesson includes a variety of worked examples, practice questions and an exam-style plenary to assess understanding.

Perfect for KS3 Maths, lower ability GCSE revision or as a foundation lesson before angle rules and properties of shapes.
