What is a Protractor?
To better understand our study of angles, we practiced using protractors to give us a more accurate determination of angle sizes. We used this website to help us. Check it out! A protractor is a semicircular geometry tool divided into 180 equal parts, each measuring 1°. It is used for drawing angles of known measures and finding angles of unknown measures and is usually made of transparent plastic, glass, steel, or wood. The geometry protractors have two scales marked on it: outer and inner. The outer scale starts from 0° and goes up to 180° in a clockwise direction, and the inner scale has the same range in the counterclockwise direction. The students really caught on quickly and had a blast!
