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 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
