upper plane angle
1angle — The meeting point of two lines or planes; the figure formed by the junction of two lines or planes; the space bounded on two sides by lines or planes that meet. For angles not listed below, see the descriptive term; e.g., axioincisal, distobuccal …
2plane — 1. A two dimensional flat surface. See planum. 2. An imaginary surface formed by extension of a point through any axis or two definite points, in reference especially to craniometry and to pelvimetry. SYN: planum. [L. planus, flat] Addison …

4Upper Atmosphere Research Satellite — The Upper Atmosphere Research Satellite (UARS) is an orbital observatory whose mission is to study the Earth’s atmosphere, particularly the protective ozone layer.The 5900 kg (13,000 lb) satellite was launched during Space Shuttle mission STS 48… …
5angle of repose — 1. physics : the angle that the plane of contact between two bodies makes with the horizontal when the upper body is just on the point of sliding : the angle whose tangent is the coefficient of friction between the two bodies 2. or angle of rest …
6Frankfurt plane — The Frankfurt plane (also called the auriculo orbital plane) was established at the World Congress on Anthropology in Frankfurt, Germany in 1884, and decreed as the anatomical position of the human skull. It was decided that a plane passing… …

8Poincaré half-plane model — Stellated regular heptagonal tiling of the model.In non Euclidean geometry, the Poincaré half plane model is the upper half plane, together with a metric, the Poincaré metric, that makes it a model of two dimensional hyperbolic geometry.It is… …
9Visual Angle Illusion — The visual angle, V degrees, subtended by a viewed object sometimes looks larger or smaller than its actual value, creating a visual angle illusion (V illusion).These V illusions have been explicitly described by many vision researchers,… …
10Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics …
