Extension of the construction from the preceding note to conoprimas with two or one fixed element

Abstract

In the preceding note, we solved the problem of transferring all kinds of constructions carried out in the plane to the system of conoprimas of points and rays; and conversely, we reduced the solutions of all kinds of problems in the secunds of conoprimas of points and rays having three fixed elements to ordinary problems in the plane. The thought naturally arises to extend the solution also to those simplest cases where in the secunds of conoprimas there are only two or only one common element.
