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 the tail plane. In our regular look at the world of kit aircraft, we meet Steve Pike and Kevin Fagan who have just finished an Australian aircraft - The Jabiru. Back at Staverton Airport, it's a milestone in Mark's Flying progress - with his first solo flight. - Like my Wheels? Mark is back on familiar ground as he fits brakes, wheels and undercarriage to his aeroplane, Martin Dovey introduces us to his vintage Kit-Plane, the Kit Fox, and it is the turn of Navigation to further perplex Mark as he continues his flying lessons. - No Longer Topless A
