Plane angles are measured by a group of instruments called Protractors. The simplest protractor comprises a semicircular disk graduated in degreesfrom to 180. It is an ancient device that was already i n use during the 13th century. Plane angles, fundamental in geometry and trigonometry, find measurement through a collection of instruments known as protractors. These tools facilitate the determination of angles, allowing for precise calculations and geometric constructions.
The basic protractor typically features a semicircular disk, its surface marked with degree graduations spanning from to 180. This ancient device, with roots tracing back to the 13th century, serves as a timeless aid for students, architects, engineers, and anyone engaged in the realms of geometry and spatial reasoning.
Protractors, in their various forms, continue to play a crucial role in education and practical applications, providing a simple yet effective means of measuring and understanding angles in the plane.
