A protractor typically consists of several key parts: the base, which provides stability; the curved edge, marked with degree measurements from 0 to 180 degrees; and the center point or pivot, which is used for rotation to align with the angle being measured. Additionally, there may be a straight edge or arm, which can be used to extend the measurement line. Some protractors also feature a transparent design for easier alignment with the angle being measured.
