Geometry is the Science of figured Space. Figured Space is of one, two, or three
dimensions, according as it consists of lines, surfaces, or solids. The boundaries
of solids are surfaces; of surfaces, lines; and of lines, points. Thus it is the
province of Geometry to investigate the properties of solids, of surfaces, and
of the figures described on surfaces. The simplest of all surfaces is the plane,
and that department of Geometry which is occupied with the lines and curves
drawn on a plane is called Plane Geometry ; that which demonstrates the prop-erties of solids, of curved surfaces, and the figures described on curved surfaces,
is Geometry of Three Dimensions. The simplest lines that can be drawn on a
plane are the right line and circle, and the study of the properties of the point,
the right line, and the circle, is the introduction to Geometry, of which it forms
an extensive and important department ....
