Porism, that, when the center of the circle falls within the triangle, the angle ABC is less than a right angle; and when the center of the circle falls outside the triangle, the angle ABC is greater than a right angle.
The last porism in the manuscript suggests a further interpretation of Euclid's results: fairness is never efficient when the society is aligned in the sense that the agents disagree primarily along one out of two political dimensions.
In the former kind, synthesis, or reversal of the analysis, constitutes an immediate demonstration of what was being sought; whereas in the latter kind, synthesis consists first in a geometrical construction or porism
, which is then followed by the demonstration.
In this paper we will concentrate on the so-called Poncelet porism for this specific setting.
The rational cases correspond to Poncelet's porism, and any rational number, except for 1/2, is related to a closed polygon, either without or with self-intersections.
This is Pappus' porism
, which was the inspiration of much of Maclaurin's work on loci, beginning in 1772 [5, p 40].
This paper is constructed as follows: first we define some terminologies such as Poncelet's traverse and Poncelet's porism in the second section.
We define a Poncelet's traverse and a Poncelet's porism in the following definitions:
