On curves of equal position of a point with a direct intersection

Abstract

These curves can serve as a guide when choosing a combination of points that is advantageous for direct intersection, and in this regard, they seem to be more rational than those shown in the diagram, 2 curves of equal accuracy. The latter curves retain their value for graphical or mechanical balancing of the position of a point determined from more than two points. In this case, using these curves, we can easily determine all the definitions of a point corresponding to a given combination and can take it into account when deriving the balanced value of the coordinates of the latter.
