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.
Who Were the Wright Brothers? On May 25, 1910, Milton Wright took his first airplane flight. He had lived a long and busy life, working for his church, raising his family, and traveling. But he had never been in an airplane. Of course, in 1910, only a handful of people had! Two people who did have flying experience were Miltonâs sons, Wilbur and Orville Wright, who had invented the airplane in 1903. Milton had watched them grow from curious and hard-working boys into two of the most famous men in the world.
