Plane, n. Etym: [F., fr. L. platanus, Gr. Place, and cf. Platane, Plantain the tree.] (Bot.)
Definition: Any tree of the genus Platanus.
Note: The Oriental plane (Platanus orientalis) is a native of Asia. It rises with a straight, smooth, branching stem to a great height, with palmated leaves, and long pendulous peduncles, sustaining several heads of small close-sitting flowers. The seeds are downy, and collected into round, rough, hard balls. The Occidental plane (Platanus occidentalis), which grows to a great height, is a native of North America, where it is popularly called sycamore, buttonwood, and buttonball, names also applied to the California species (Platanus racemosa).
Plane, a. Etym: [L. planus: cf. F. plan. See Plan, a.]
Definition: Without elevations or depressions; even; level; flat; lying in, or constituting, a plane; as, a plane surface.
Note: In science, this word (instead of plain) is almost exclusively used to designate a flat or level surface. Plane angle, the angle included between two straight lines in a plane.
– Plane chart, Plane curve. See under Chart and Curve.
– Plane figure, 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 figure.
– Plane geometry, that part of geometry which treats of the relations and properties of plane figures.
– Plane problem, a problem which can be solved geometrically by the aid of the right line and circle only.
– Plane sailing (Naut.), the method of computing a ship's place and course on the supposition that the earth's surface is a plane.
– Plane scale (Naut.), a scale for the use of navigators, on which are graduated chords, sines, tangents, secants, rhumbs, geographical miles, etc.
