Used Protractor

A protractor is a tool used to measure or draw angles. It usually consists of a metal plate with a scale or goniometer (degree meter) and a movable arm or blade that can be moved along the scale. Protractors can be made in different sizes and shapes, depending on the type of measurement for which they are to be used. Some protractors have a digital display that makes measurements more accurate and makes reading angles easier. There are several types of protractors, such as miter protractors, which are specifically designed for measuring miter angles in woodworking and other applications, and precision protractors, which are used for measuring very accurate angles in manufacturing and metrology. Protractors are used in a wide variety of applications, including woodworking, welding, machine component manufacturing, and architecture.
