    The units of measurement used with angle protractors are degrees. A degree is a unit of measurement for angles, where one complete rotation around a circle is divided into 360 degrees. The protractor typically has a semicircular shape and is marked with a scale that ranges from 0 to 180 degrees, with each degree further divided into minutes and seconds for more precise measurements. Some protractors may also have a full circle scale with 360 degrees for more advanced applications.
