A protractor typically consists of a semicircular or circular body marked with degree measurements, usually from 0 to 180 degrees for a semicircular protractor or 0 to 360 degrees for a full protractor. It has a straight edge for aligning with the vertex of an angle, often referred to as the baseline. Additionally, many protractors feature a pivot point or a small hole at the center for precise placement over an angle's vertex. Some protractors also include an inner scale for measuring angles in radians.
