Protractor (angle Measurement Tool)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
A protractor is an essential measuring instrument used to determine and construct angles. Typically made of transparent plastic or metal, it features a semicircular or circular scale marked in degrees from 0° to 180° (or 360° for full circle protractors), allowing users to measure, draw, or replicate specific angles accurately. Widely utilized in education, engineering, architecture, and various technical fields, the protractor facilitates precise geometric work and spatial understanding.
