  A protractor gives a clockwise degree scale and an anticlockwise degree scale.
                         You choose the correct scale by finding the one that starts with 0° on the angle
                         arm. Look at where the other angle arm passes under the degree scale. That is
                         where your measurement is.




















                        You can also place the protractor on the angle using the other arm. Then the
                         correct position looks like this:
   1   2   3   4   5
