Protractors

Protractors are essential measuring tools used to determine angles with accuracy and ease. Commonly made from plastic, metal, or stainless steel, they are widely used in education, engineering, construction, and drafting. A standard protractor measures angles in degrees, typically ranging from 0° to 180° or 0° to 360°.

They come in various types, including semicircular, circular, and digital protractors, each suited for specific applications. Whether for classroom geometry or professional layout work, protractors help ensure precision in angle measurement. Their simple design and reliability make them a fundamental tool for students, engineers, and tradespeople alike.
