...said in Geometry to be plane; and we have its definition as follows : — A Plane, or a Plane Surface, is that in which any two points being taken, the straight line between them lies wholly in that surface. We shall obtain a simpler definition in a future chapter. In the present treatise plane surfaces... | |
