Publisher's Synopsis
Excerpt from Elementary Geometry Plane and Solid: For Use in High Schools and Academies
When we speak of a point or a line, a straight line or a crooked line, everybody knows in a general way what is meant. In the minds of persons not familiar with the strict sense in which these terms are used in Geometry, it may be that the words point' and line are associated with marks of some sort, made for example with a pen or pencil; they may think of a point as a dot, and of a line as a long, narrow mark, but in spite of this association the true meaning of the terms 'point, ' 'line, ' straight, ' 'crooked, ' etc., is pretty clearly understood.
It is not at all certain that definitions could be given in words which would convey an intelligent idea of the meaning of these terms to a person not already familiar with the thought conveyed by them, still a few words of comment may serve to fix the attention upon some properties of points and lines which are fundamental in the study of Geometry.
