Fixed-gear bicycle — A fixed gear bicycle or fixed wheel bicycle, is a bicycle without the ability to coast. The sprocket is screwed directly on to the hub and there is no freewheel mechanism. A reverse thread lockring is usually fitted to prevent the sprocket from… … Wikipedia
fixed-wing aircraft — An airplane or glider whose wing is rigidly attached to the structure, or is otherwise adjustable. The term is used to refer to monoplanes, biplanes, triplanes, and, in fact, all conventional aircraft that are neither balloons, airships,… … Aviation dictionary
variable-geometry aircraft — An aircraft whose shape can be changed. The term, however, is generally used for aircraft whose sweepback can be varied in flight. See fixed geometry … Aviation dictionary

Similarity (geometry) — Geometry = Two geometrical objects are called similar if one is congruent to the result of a uniform scaling (enlarging or shrinking) of the other. One can be obtained from the other by uniformly stretching , possibly with additional rotation,… … Wikipedia
Differential geometry of surfaces — Carl Friedrich Gauss in 1828 In mathematics, the differential geometry of surfaces deals with smooth surfaces with various additional structures, most often, a Riemannian metric. Surfaces have been extensively studied from various perspectives:… … Wikipedia
Glossary of arithmetic and Diophantine geometry — This is a glossary of arithmetic and Diophantine geometry in mathematics, areas growing out of the traditional study of Diophantine equations to encompass large parts of number theory and algebraic geometry.
