* Abduction ( kinesiology ), a type of movement which draws a limb away from the median plane of the body

The most familiar type of mirror is the plane mirror, which has a flat surface.

One type of solution represents an electron moving indefinitely through the crystal as a plane wave ; the particular solutions for a periodic regular crystal lattice are called Bloch functions.

The nebulae of the last type show the strongest concentration to the galactic plane and their progenitors are therefore relatively young massive stars.

In the case of the circularly polarized light, the field strength remains constant from plane to plane but its direction steadily changes in a rotary type manner.

Perhaps the most familiar type is the toy paper plane.

* Arc ( projective geometry ), a particular type of set of points of a projective plane

The combination of a rotation and translation in the plane R < sup > 2 </ sup > can be represented by a certain type of 3x3 matrix known as a homogeneous transform.

Unlike older systems like the Link Trainer, the system they envisioned would have a considerably more realistic aerodynamics model that could be adapted to any type of plane.

This provided the plane spotter at San Juan with another interesting aircraft type to look out for, but did little for the airline other than help increase the earnings from the Virgin Islands routes.

Here is a type synonym for points in the plane, and functions computing the distances between two points, and the area of a triangle with the given corners as per Heron's formula.

Though lacking in evidence, perhaps the most common explanation is that World War II ( 1939 – 1945 ) aircraft machine gun belts were nine yards long ; there are many versions of this explanation with variations regarding type of plane, nationality of gunner, and geographic area.

* Graphic type: Bitmap, 2 plane bitpacked

In 1998, another first plane of a new type arrived when the airline's first Airbus A319 joined the fleet.

This additional type of sound wave ( additional type of elastic wave ) travels only in solids, and the sideways shearing motion may take place in any direction at right angles to the direction of wave-travel ( only one shear direction is shown here, at right angles to the plane ).

A listric fault is a type of fault in which the fault plane is curved.

It is the only surviving example of this type of plane.

The Skimmer plane is the only flyable fixed wing aircraft in Vice City, and because it features pontoons and is normally found in water, it is a floatplane, a type of seaplane.

The second principal type in North Europe has, as its most characteristic feature, a pronounced rectangular suspension loop set in the same plane as the bow, as found amongst the Hungarian examples, and is predominantly centered in Denmark and England during the later 10th and 11th centuries.

Upsilon Andromedae B is a red dwarf of spectral type M4. 5V located at a distance ( in the plane of the sky ) of 750 AU from the primary star.

In 1911, Curtiss unveiled a development of his floatplane experiments married to a larger version of his successful Curtiss Model D land plane, but with a larger engine and a rudimentary hull and fuselage, designated as the Model E. This was the first air plane with a hull, and arguably the creation of the " flying boat " type that dominated long distance air travel for the next four to five decades.

In geometry, inversive geometry is the study of those properties of figures that are preserved by a generalization of a type of transformation of the Euclidean plane, called inversion.

Word of Dag Hammarskjold's death in an African plane crash has sent a shockwave around the globe.

Hence, thought of as a line in a particular plane **yp, any tangent to Q has a unique image and moreover this image is the same for all planes through L.

For any pencil in a plane containing a Af-fold secant of **zg has an image regulus which meets the plane of the pencil in Af lines, namely the images of the lines of the pencil which pass through the intersection of **zg and the multiple secant, plus an additional component to account for the intersections of the images of the general lines of the pencil.

`` For three days now a German reconnaissance plane has been over the city taking pictures.

This is not only a compliment to Mijbil, of whom there are a fine series of photographs and drawings in the book, but to the author who has catalogued the saga of a frightened otter cub's journey by plane from Iraq to London, then by train ( where he lay curled in the wash basin playing with the water tap ) to Camusfearna, with affectionate detail.

Members of the family are usually perennial herbs with sword-shaped unifacial leaves ; the inflorescence is a spike or panicle of solitary flowers, or forms a monochasial cyme or rhipidium ( meaning that the successive stems of the flowers follow a zig-zag path in the same plane ); and the flower has only three stamens, each opposite to an outer tepal.

In analytic geometry, the plane is given a coordinate system, by which every point has a pair of real number coordinates.

All that at present can be attempted is, to reproduce a single plane in another plane ; but even this has not been altogether satisfactorily accomplished, aberrations always occur, and it is improbable that these will ever be entirely corrected.

On the one hand, Bernard Bolzano ( 1817 ) had been aware that any bounded sequence of points ( in the line or plane, for instance ) has a subsequence that must eventually get arbitrarily close to some other point, called a limit point.

If a simply stable system response neither decays nor grows over time, and has no oscillations, it is marginally stable: in this case the system transfer function has non-repeated poles at complex plane origin ( i. e. their real and complex component is zero in the continuous time case ).

Crochet has been used by mathematician Daina Taimina in order to create a version of the hyperbolic plane.

The center of an atomic projectile striking this plane has geometrically a definite probability of passing within a certain distance of one of these points.

The rotation itself is represented by the angular velocity vector Ω, which is normal to the plane of the orbit ( using the right-hand rule ) and has magnitude given by:

* a triangle: A plane figure that has 3 straight bounding sides.

* a quadrilateral: A plane figure that has 4 straight bounding sides.

A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it ( for example, to locate a point on the surface of a sphere you need both its latitude and its longitude ).

Likewise, if he / she chooses to observe the interference pattern, then he / she has no influence whatsoever over where in the observation plane he / she will observe a specific particle.

* In the plane ( d = 2 ), if there are b vertices on the convex hull, then any triangulation of the points has at most 2n − 2 − b triangles, plus one exterior face ( see Euler characteristic ).

* In the plane, each vertex has on average six surrounding triangles.

Many results about plane figures are proved, e. g., If a triangle has two equal angles, then the sides subtended by the angles are equal.

Once the Euclidean plane has been described in this language, it is actually a simple matter to extend its concept to arbitrary dimensions.

If any part of the ball reaches any part of the imaginary vertical plane transected by this line while in-bounds and in possession of a player whose team is striving toward that end of the field, this is considered a touchdown and scores six points for the team whose player has advanced the ball to, or recovered the ball in, this position.
