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]
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 ...
The convex hull of the lute is a kite shape with three 108° angles and one 36° angle. [2] The sizes of any two consecutive pentagrams in the sequence are in the golden ratio to each other, and many other instances of the golden ratio appear within the lute.
A man flying a kite on the beach, a good location for flying as winds travelling across the sea contain few up or down draughts which cause kites to fly erratically. There are safety issues involved in kite-flying. Kite lines can strike and tangle on electrical power lines, causing power blackouts and running the risk of electrocuting the kite ...
Colorful delta-wing kite... Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind (or towing) for generation of airflow over the lifting surfaces. Various types of kites exist, [1] depending on features such as material, shape, use, or operating skills,Wind required. Kites may fly in air, water, or other fluids ...
The male humpback whale that traveled the longest documented distance to date is observed in Zanzibar Channel, off the village of Fumba on the Tanzanian island of Unguja, on August 22, 2022.
Not every parallelogram is a rhombus, though any parallelogram with perpendicular diagonals (the second property) is a rhombus. In general, any quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a kite. Every rhombus is a kite, and any quadrilateral that is both a kite and parallelogram is a rhombus.
