A protractor is typically made of plastic or acrylic, although some are made from metal or wood. Plastic protractors are lightweight and durable, making them ideal for school use, while metal protractors offer added sturdiness and precision. The material is often transparent or semi-transparent to allow for easy reading of measurements. Some protractors also feature printed markings for angles, usually in degrees.
