Tips: What is an angle protractor?

An angle protractor is a tool used for measuring angles in geometry. It typically consists of a flat, semi-circular or circular piece of clear plastic or metal, with an arc marked in degrees or radians. The protractor may also have a straight edge or ruler attached to one of its sides.

To use an angle protractor, you place the center point of the protractor at the vertex of the angle you want to measure, aligning one of the straight edges with one of the sides of the angle. You can then read the angle measurement off the arc, usually in degrees or radians.

Angle protractors are commonly used in various applications, such as in carpentry, engineering, drafting, and mathematics, among others. They are essential tools for measuring and constructing accurate angles, which are fundamental to many geometric concepts and constructions.
