About This Product
A protractor is a drawing instrument used to measure an angle or to mark an angle of a chosen size. The centre of the straight edge is placed on the vertex of the angle, the base line is lined up with one arm, and the reading is taken where the other arm meets the scale. A transparent protractor lets the drawing show through while it is used. In geometry and technical drawing lessons, students use it with a Triangular Scale to set out angles and lengths.
