Hexagon on the circumcircle of an acute triangle at the six points (including three triangle vertices) where the extended altitudes of the triangle meet the circumcircle, then the area of the hexagon is twice the area of the triangle. Let ABCDEF be a hexagon formed by six tangent lines of a conic section. Then Brianchon's theorem states that the three main diagonals AD, BE, and CF intersect at a single point. In a hexagon that is tangential to a circle and that has consecutive sides "a", "b", "c", "d", "e", and "f", If an equilateral triangle is constructed externally on each
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
