What is a "protractor"?
A protractor is a tool used to measure and draw angles. It is usually a flat, semicircular or circular device marked with degree measurements from 0 to 180 or 360. The protractor has a straight edge for aligning with a line or point, while the curved side is used to measure the angle between two meeting lines. Protractors are commonly used in geometry, drafting, carpentry, and construction to ensure accurate angle measurements for various projects. They come in different sizes and types, including digital versions for easier reading.
