Hexagon side of any hexagon, then the midpoints of the segments connecting the centroids of opposite triangles form another equilateral triangle. A skew hexagon is a skew polygon with 6 vertices and edges but not existing on the same plane. The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes. A regular skew hexagon is vertex-transitive with equal edge lengths. In 3-dimensions it will be a zig-zag skew hexagon and can be seen in the vertices and side edges of a triangular antiprism with the same D, [2,6] symmetry, order
A Plane Is Born A Plane Is Born A Plane is Born, presented by Mark Evans, was a 15 part series for Discovery Home and Leisure (now Discovery Real Time), in which he not only learned to fly but also built his own Europa two-seater aeroplane. During the course of the series, he tackled everything from the composite control surfaces to the installation of the engine. The series took the viewer for the first time through the step-by-step process of building a 200 mph kit aircraft, capable of flying from England to the South of France on a single tank of fuel. - Research
