According to the given image, Annabelle measured the angle without lining up one side of the angle with 0° on the protractor.

So, we can say that Annabelle is not using the protractor correctly, the image below shows the right way.

The horizontal red line refers to the side of the angle that has to be lined up with 0° on the protractor.
