The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure, in contrast to the special cases below.
It was designed and built by the Wright brothers. They flew it four times on December 17, 1903, near Kill Devil Hills, about four miles south of Kitty Hawk, North Carolina, US. Today, the airplane is exhibited in the National Air and Space Museum in Washington D.C.
First flight claims are made for Ader, Whitehead, Richard Pearse, and Karl Jatho for their variously documented tests in years prior to and including 1903. Claims that the first true flight occurred after 1903 are made for Traian Vuia and Santos-Dumont.ilbur was born near Millville, Indiana, in 1867; Orville in Dayton, Ohio, in 1871. The brothers never married. The other Wright siblings were named Reuchlin (1861â1920), Lorin (1862â1939), Katharine (1874â1929), and twins Otis and Ida (born 1870, died in infancy).
