Protractors

A protractor is a geometric tool used for measuring angles in geometry, engineering, and various technical applications. It typically consists of a flat, semi-circular or circular piece of transparent or opaque material with degree markings along its edge. The center of the protractor is marked by a point that corresponds to the vertex of the angle being measured. Protractors are essential tools in geometry, trigonometry, and various technical disciplines where angle measurements play a crucial role. They are commonly used by students, architects, engineers, and anyone involved in tasks that require accurate angle measurements, such as drawing, drafting, and construction.
