Protractor Protractor A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts. Some precision protractors further divide degrees into arcminutes. They are used for a variety of mechanical and engineering-related applications. One 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. A bevel protractor is a graduated
China's Circular Economy Germany and Japan, where they have shaped many of China's policies revolving around the three R's of re-use, reduce, recycle. Japan's Basic "Law for Establishing Promoting the Creation of a Recycling-Oriented Society" and Germany's "Closed Substance Cycle and Waste Management Act" has been the greatest influence on China's circular economy strategies. Japan has been successful influencing whole industries into adopting sustainability strategies, where they view recycling measures as a competitive advantage rather than a liability. China has learned from this by making EIP's and industry-wide recycling initiatives as core functions of their circular economy. Germany has been effective in promoting
