Follow the scale starting with zero around until you find the value the line crosses at
Decide which side of the protractor you are using by finding where the bottom of the angle crosses 0
Check your answer is the correct type of angle - if you have an acute answer is the angle you are measuring acute
Place the protractor on the angle with the point of the angle at the centre of the protractor
