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 packed programme sees major progress on the plane with the rudder assembly completed and the fuselage top on and finally bonded. Back at Staverton, Mark learns how to talk - important for a presenter but vital for a pilot as he masters the rudiments of radio communication. In another look at other kit-planes, we meet fellow Europa constructor Peter Kember who was the first ever to home-build a Europa Kit. - All Revved Up It's a red-letter day down at the workshop as the brand new engine arrives with Europa's Andy Draper. Mark takes on the delicate task of fitting
