A protractor is a measuring instrument used in geometry and mathematics to quantify angles. It typically consists of a flat, semicircular or circular tool made of transparent or opaque material, marked with degree measurements from 0 to 180 or 0 to 360. The center of the protractor usually has a pivot point, allowing it to be placed at the vertex of an angle for accurate measurement. Users align the protractor’s baseline with one side of the angle and read the degree value where the other side intersects the protractor scale to determine the angle’s measurement. Protractors come in various designs, including simple plastic versions for basic measurements and more advanced models with additional features for specific applications.
