1. Angles Recognising different types of angles

2. What type of angle is this? Right angle

3. What type of angle is this? acute

4. What type of angle is this? obtuse

5. What type of angle is this? acute

6. What type of angle is this? reflex

7. What type of angle is this? obtuse

8. A reminder… Right angles are 90 o. Acute angles are less than 90 o. Obtuse angles are more than 90 o but less than 180 o. Reflex angles are more than 180 o.

9. Our objectives: To be able to identify, estimate, measure and order acute and obtuse angles. To improve our accuracy when using protractors.
