A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol The degree symbol is a typographical symbol, or glyph, that is used to represent degrees of arc (see Geographic coordinate system ) or temperature. In medical shorthand, the degree symbol is also used to denote hours, for instance q4° or q4° meaning "every four hours."), is a measurement of plane In mathematics, a plane is any flat, two-dimensional surface. A plane is the two dimensional analogue of a point , a line (one-dimension) and a cube (three-dimensions). Planes can arise as subspaces of some higher dimensional space, as with the walls of a room, or they may enjoy an independent existence in their own right, as in the setting of angle In geometry and trigonometry, an angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle (Sidorov 2001). 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 ray is rotated about the, representing 1⁄360 of a full rotation A turn is a unit of plane angle, equal to 360° or 2π radians. As an angular unit it is mainly useful for large angles, such as in connection with coils and rotating objects. See also winding number; one degree is equivalent to π/180 radians The radian is represented by the symbol "rad" or, more rarely, by the superscript c . For example, an angle of 1.2 radians would be written as "1.2 rad" or "1.2c" (the second symbol is often mistaken for a degree: "1.2°"). However, the radian is mathematically considered a "pure number" that needs. When that angle is with respect to a reference meridian A meridian is an imaginary arc on the Earth's surface from the North Pole to the South Pole that connects all locations running along it with a given longitude. The position of a point on the meridian is given by the latitude. Each meridian is perpendicular to all circles of latitude at the intersection points. Each is also the same size, being, it indicates a location along a great circle A great circle of a sphere is a circle that runs along the surface of that sphere so as to cut it into two equal halves, as distinct from a small circle. The great circle therefore has both the same circumference and the same center as the sphere. It is the largest circle that can be drawn on a given sphere of a sphere A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in three dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point. This distance r is known as the radius of the sphere. The, such as Earth (see Geographic coordinate system A geographic coordinate system is a coordinate system that enables every location on Earth to be specified in three coordinates, using mainly a spherical coordinate system), Mars Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the, or the celestial sphere In astronomy and navigation, the celestial sphere is an imaginary sphere of arbitrarily large radius, concentric with the Earth and rotating upon the same axis. All objects in the sky can be thought of as projected upon the celestial sphere. Projected upward from Earth's equator and poles are the celestial equator and the celestial poles. The.[1]
