Hexagon them. Coxeter states that every zonogon (a 2"m"-gon whose opposite sides are parallel and of equal length) can be dissected into "m"("m"-1)/2 parallelograms. In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. This decomposition of a regular hexagon is based on a Petrie polygon projection of a cube, with 3 of 6 square faces. Other parallelogons and projective directions of the cube are dissected within rectangular cuboids. A regular hexagon has Schläfli symbol {6}. A regular hexagon is a part of the regular hexagonal tiling, {6,3}, with 3 hexagonal
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
