Bilateral comparison in angle

Project Description

Five angle blocks of 10", 5', 30', 5° and 30° will be measured by the participants. The angle blocks will be KOBA blocks with a measuring face of 50 x 8 mm. The angle blocks used are basically a polygon but with only two faces. These blocks, like polygons, also have pyramidal errors. The angle is defined by the angle between the measuring faces with the plane perpendicular to the line being common to both functional planes.
