1. Protractor

   A protractor is a square, circular or semicircular tool, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees. Radian-scale protractors measure angles in radians. They are used for a variety of mechanical and engineering-related applications, but perhaps the most common use is in geometry lessons in schools. Some protractors are simple half-discs. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle.
