Hexagon circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point. If the successive sides of a cyclic hexagon are "a", "b", "c", "d", "e", "f", then the three main diagonals intersect in a single point if and only if . If, for each side of a cyclic hexagon, the adjacent sides are extended to their intersection, forming a triangle exterior to the given side, then the segments connecting the circumcenters of opposite triangles are concurrent. If a hexagon has vertices
Snakes on a Plane landing, the plane makes it to the terminal. The passengers leave the plane and antivenom is given to those who need it. Just as Flynn and Sean are about to disembark the plane, a final snake jumps out and bites Sean in the chest.
