Protractors

A protractor is a simple measuring tool used to determine angles in various fields such as geometry, engineering, and crafting. Typically shaped like a half-circle or a full circle, it is marked with degrees from 0 to 180 or 0 to 360. To use a protractor, you place its center point over the angle's vertex and align one side of the angle with the baseline of the protractor. You can then read the corresponding measurement on the scale. Protractors are essential for precision in tasks that involve angles, such as drawing, construction, and design.
