Angle print that page

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

Angle of view print that page

Focal_length

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

Contact angle print that page

File-Water_droplet_at_DWR-coated_surface1

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

Northwest Angle print that page

Lake_of_da_woods

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

Dutch angle print that page

Battlefield_earth_planetship

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

Degree (angle) print that page

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

Hour angle print that page

In astronomy and celestial navigation, the hour angle is one of the coordinates used in the equatorial coordinate system to give the position of a point on the celestial sphere . The hour angle of a point is the angle between the plane containing the Earth's axis and the zenith (the

Angle trisection print that page

Lineale

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

Small-angle X-ray scattering print that page

the separation of the weak scattered intensity from the strong main beam. The smaller the desired angle , the more difficult this becomes. The problem is comparable to one encountered when trying to observe a weakly radiant object close to the sun, like the sun's corona. Only if the moon blocks

Pressure angle print that page

Pressure_profile

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
