Protractors are tools used to measure and draw angles in drafting, mathematics, and engineering. They consist of a circular or semicircular device marked with degree markings, allowing users to accurately measure and set angles. Protractors are essential for creating geometric shapes, measuring angles in technical drawings, and performing mathematical calculations involving angles.
