Protractors
Protractors are a handy tool used to measure and draw angles. Typically semi-circular in shape, protractors are also available in full-circle, 360-degree versions. Angles are given in clearly defined increments, with each degree precisely delivered from 0 to 360. Easily identify acute, right, or obtuse angles with protractors made in stainless steel, plastic, and digital formats. Specialized protractors deliver many features such as built-in angle pitch calculators, a magnetic base for support, and digital readout displays.
