Abstract: A medico-scientific measuring device of a substantially flat transparent material having a base edge and a half circle with an outer edge suitably marked for measuring angles; a horizontal plot line and a center point as a vertex adjacent to the base edge; a plurality of plot lines from the outer edge toward converging on the center point defining specific angles; a floating point indicia adjacent to, and in communication with, the center point; and a visible vertex gap axial from the floating point such that the horizontal plot lines and the converging plot lines are substantially interrupted to thereby facilitate a more accurate placement of the vertex and to provide a more accurate angle determination.
