    • Abstract

       

      The article discusses a simplemethod to find the angle ofminimumdeviation of a general prism, not necessarily equilateralor isosceles. The method uses a single measurement andrequires a compass, ruler, some pins, and no additional material.It is precise and accurate. We present the method firstand then the justification.
