Hexagon Hexagon In geometry, a hexagon (from Greek ἕξ "hex", "six" and γωνία, "gonía", "corner, angle") is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°. A "regular hexagon" has Schläfli symbol {1} and can also be constructed as a truncated equilateral triangle, t{3}, which alternates two types of edges. A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle). The common length of the sides equals the radius
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
