**How a protractor works and using a protractor**

What is the angle of these arcs?

Work on the back page of your Angles booklet to show your understanding of measuring angles.

**Constructing Angles**

Practise creating the following angles:

a) 35

b) 90

c) 160

a) 35

**°**b) 90

**°**c) 160

**°**

d) an angle less than 90**°****e) an angle greater than 90****°****f) an angle of your choice, make sure you classify it.****Classifying angles and estimating**

Consider the following things when estimating angles:

1. Is it more or less than 90

2. Is it closer to 90

3. What angle would it be classified as?

4. Can you create, estimate and classify three of your own angles?

1. Is it more or less than 90

**°**(a perfect corner?)2. Is it closer to 90

**°**, the end of the protractor or in the middle?3. What angle would it be classified as?

4. Can you create, estimate and classify three of your own angles?
