length distance angle
1Length — is the long dimension of any object. The length of a thing is the distance between its ends, its linear extent as measured from end to end. This may be distinguished from height, which is vertical extent, and width or breadth, which are the… …
2Angle of view — In photography, angle of view describes the angular extent of a given scene that is imaged by a camera. It parallels, and may be used interchangeably with, the more general visual term field of view.It is important to distinguish the angle of… …
3Angle trisection — The problem of trisecting the angle is a classic problem of compass and straightedge constructions of ancient Greek mathematics.Two tools are allowed # An un marked straightedge, and # a compass, Problem: construct an angle one third a given… …

5Distance focale équivalente en 35 mm — En photographie, la distance focale équivalente en 35 mm est une mesure qui indique l angle de vue d une combinaison particulière d un objectif d appareil photo avec une taille de film ou de capteur. Le terme provient de l époque où la… …
6Angle of parallelism — In hyperbolic geometry, the angle of parallelism Φ is the angle at one vertex of a right hyperbolic triangle that has two asymptotic parallel sides. The angle depends on the segment length a between the right angle and the vertex of the angle of… …

8Optimum HDTV viewing distance — is the distance that provides the viewer with the optimum immersive visual HDTV experience. Although opinions vary on the exact screen size to distance relationship, formal research and recommendations suggest closer is preferred to further[not… …
9Focal length — The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. Thin lens approximation For… …
10Arc length — Determining the length of an irregular arc segment is also called rectification of a curve. Historically, many methods were used for specific curves. The advent of infinitesimal calculus led to a general formula that provides closed form… …
