The Iron Triangle (film) The Iron Triangle (film) The Iron Triangle is a 1989 film about the Vietnam War shot in Sri Lanka and directed by Eric Weston. The story is based on the diary of an unknown Viet Cong Soldier. This unique fact gives the movie a different perspective than many of the other movies about the Vietnam war and makes black and white distinctions about who were the "good guys" and "bad guys" a little more complicated. The film stars Beau Bridges, Haing S. Ngor, Liem Whatley, Johnny Hallyday, Jim Ishida, and Ping Wu. Each character helps bring to life the struggle
Hyperbolic triangle the third angle. The triangle where two vertices are ideal points and the remaining angle is right, one of the first hyperbolic triangles (1818) described by Ferdinand Karl Schweikart. The triangle where all vertices are ideal points, an ideal triangle is the largest possible triangle in hyperbolic geometry because of the zero sum of the angles. The relations among the angles and sides are analogous to those of spherical trigonometry; the length scale for both spherical geometry and hyperbolic geometry can for example be defined as the length of a side of an equilateral triangle with fixed angles. The length
