A separate article is about kite flying.
In geometry, a kite or deltoid is a type of quadrilateral, a four-sided polygon. It has two pairs of equal sides, and the two sides in each pair are adjacent. (contrast with the parallelogram, where the sides of each pair are opposite.)
It is also an object that opposes the force of the wind with the tension of a string held by the operator. The latter term was inspired by the former.
The area A of the deltoid equals A = (e f)/2, where e and f are the lenghts of the diagonals.
