The standard 180º protractor has two scales. The inside scale measures angles from the right. The outside scale measures angles from the left.
The standard protractor is thus confusing as many learners are not sure which scale to use.
The new Angler protractor has two scales but only one is visible. The other scale is hidden on the other side. This erases the confusion of two scales.
The new protractor is clear and easy to use - perfect for those wishing to use a 180º protractor but wanting the benefits of a 360º protractor!
