1. BRAIN-TEASER! Work with a partner. Examine the picture. What are the different types of angles that you see? Where are they? Tell the rest of the class about your answers!

2. Class discussion: What can we use to measure angles accurately? Take a good look at the sketch - or at your own protractor. How do we use the protractor to measure angles?

Learning Outcome 4:The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts. Assessment Standard 4.11: We know this when the learner recognises and describes angles in two-dimensional shapes, three-dimensional objects and the environment.
