exclusively used to designate a flat or level surface.
, the angle included between two straight lines
in a plane.
, Plane curve
. See under Chart
, a figure all points of which lie in the same
plane. If bounded by straight lines it is a rectilinear
plane figure, if by curved lines it is a curvilinear plane
, that part of geometry which treats of the
relations and properties of plane figures.
, a problem which can be solved geometrically
by the aid of the right line and circle only.

place and course on the supposition that the earth's
surface is a plane.
(Naut.), a scale for the use of navigators, on

through three points of the curve, it passes through all
the other points of the curve. Any other curve is called a
curve of double curvature
