to fly them Answer Alexander Wilson in 1749 was the first person to use a kite for scientific investigation. He measured the temperature as different heights using a train of kites to hold several thermometers aloft upto a height of around 3,00ft. This was also the first written account of a train of kites being used. He performed the experiment at Camlachie in Scotland. Benjamin Franklin did his famous lightning experiment in 1752.

All kites are quadrilaterals, but quadrilaterals are not kites.
No, kites do not have congruent diagonals.
No, some kites fly badly with a tail. The tail add stability to a badly balanced kite but it also adds weight so can drag a gently pulling kite down. Unless a kite is homemade or asymetric in design it should be well balanced. As most kites are now mass produced and quite accurate people mostly use them to look pretty! A few kites (Sodi's) have rope tails to add weight at the base and produce the correct angle of attact to the wind. A looped tail made from a single piece of fabric and attached at two points on the base of the kite is used on some kites such as smaller sleds to add to the lift. Kites such as box kites and tetrahedral kites are stable without tails. The most common kite requiring a tail is the flat diamond kite.
Not all trapezoids are kites. A trapezoid is a 4-sided figure with a pair of parallel sides, so any item, not just kites, can manifest this shape.
