Abstract
The paper discusses finite or infinite incidence planes in which an oval plays the role of a metric conic. The points of the oval are used as coordinates, and ordered couples of these coordinates give rise to a coordinatization of the whole plane by means of ternary structures. These ternaries are studied, and a few specializations and their geometric analogues are studied.
