Concurrency in Hexagons -- A Trigonometric Tale
Dept. of Mathematics, University of North Texas, Denton, TX 76203, U.S.A.
It is shown that the concurrency of the main diagonals in a hexagon is equivalent to a nine-angle sine trigonometric identity. Applications and generalizations to hexagonal paths are also discussed.
Keywords: Hexagon, main diagonals, concurrency, collinearity, cross ratio, sine-theorems.
