In geometry , an **angle** is the figure formed by two rays sharing a common endpoint , called the vertex of the **angle** . [ 1 ] The magnitude of the **angle** is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one

In photography , **angle** of view describes the angular extent of a given scene that is imaged by a camera . It is used interchangeably with the more general term field of view . It is important to distinguish the **angle** of view from the **angle** of coverage , which describes the **angle** of projection

The contact **angle** is the **angle** at which a liquid / vapor interface meets a solid surface . The contact **angle** is specific for any given system and is determined by the interactions across the three interfaces. Most often the concept is illustrated with a small liquid droplet resting on

The Northwest **Angle** , known simply as the **Angle** by locals, and coextensive with **Angle** Township , is a part of northern Lake of the Woods County, Minnesota , and is the only place in the United States outside Alaska that is north of the 49th parallel . That parallel is the northern boundary

A special Dutch **Angle** is the Bavarian **Angle** , where the camera position is changed about 90° from the common **angle** . Horizontal lines become vertical. A Dutch **angle** differs from a high **angle** shot and low **angle** shot (although Dutch **angle** shots are often combined with those for artistic

A degree (in full, a degree of arc , arc degree , or arcdegree ), usually denoted by ° (the degree symbol ), is a measurement of plane **angle** , representing 1 ⁄ 360 of a full rotation ; one degree is equivalent to π/180 radians . It is not an SI unit , as the SI unit for angles is radian

With such tools, the task of **angle** trisection is generally impossible , as shown by Pierre Wantzel (1837). Wantzel's proof relies on ideas from the field of Galois theory —in particular, trisection of an **angle** corresponds to the solution of a certain cubic equation , which is not possible

described by the Fresnel equations , and is dependent upon the incoming light's polarization and **angle** of incidence. The Fresnel equations predict that light with the p polarization ( electric field polarized in the same plane as the incident ray and the surface normal ) will not be reflected

Camber **angle** alters the handling qualities of a particular suspension design; in particular, negative camber improves grip when cornering. This is because it places the tire at a better **angle** to the road, transmitting the forces through the vertical plane of the tire, rather than through

Just as there are three types of profile angles, there are also three types of corresponding pressure angles: the transverse pressure **angle** , the normal pressure **angle** , and the axial pressure **angle** . [ 3 ] [ edit ] See also List of gear nomenclature [ edit ] References ^ http
