Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape [10] [11] and which are in turn named for a hovering bird and the sound it makes. [12] [13] According to Olaus Henrici, the name "kite" was given to these shapes by James Joseph Sylvester. [14]
Various kites being flown Star-shaped kite above a meadow south of Hockenheim. This sparless, ram-air inflated kite, has a complex bridle formed of many strings attached to the face of the wing. A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. [2]
Kites in other media like water, soil, or plasma have speeds specific to their conditions. Speed is relative to the activity and purpose. Kite-fishing requires speed.

In Euclidean geometry, a right kite is a kite (a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other) that can be inscribed in a circle. [1] That is, it is a kite with a circumcircle (i.e., a cyclic kite). Thus the right kite is a convex quadrilateral and has two opposite right ...
A tetrahedral kite is a multicelled rigid box kite composed of tetrahedrally shaped cells to create a kind of tetrahedral truss. The cells are usually arranged in such a way that the entire kite is also a regular tetrahedron. The kite can be described as a compound dihedral kite as well. An early design of the tetrahedron kite from Alexander ...
In addition, birds need keel-shaped sternums for flight, and ostrich sternums are too flat. They may not be capable of flight, but ostriches can run — and they can run fast. Ostriches can keep ...
"They are typically easy to prepare and, due to their smaller size and thinner shape, cook through quickly." A 4-ounce serving of chicken tenderloins provides 110 calories, 25 grams of protein and ...
A kite flying on a 200-metre (220 yd) line will have twice as much available wind energy as a kite on a 10-metre (33 ft) line. [20] A kite's shape blocks air like a traditional sail and acts as an aerofoil, with the combined forces of lift and drag pulling the boat through the water. [21]
