Their contention is that he gave the essential idea to Descartes in a letter. Finally, if the four points do not all lie on one line, some set of three must form a triangle, and we can rename them if necessary so that this triangle is ABC and the remaining point possibly lying on one side of the triangle is D.Custave Flaubert All the transformations so far considered have taken points into points.Perhaps the inferior status of geometry in the school curriculum stems from a lack of familiarity on the part of educators with the nature of geometry and with advances that have taken place in its development.
