The Iron Triangle (film) of what it means to fight for one's country. Whether they be a simple farmer's son (Ho), a French mercenary (Jacques), or a simple soldier (Keene) these three men bring to light a gray view of war which reflects that there are many sides to the war than just "good" or "evil". 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
Triangle their internal angles, measured here in degrees. A triangle that has two angles with the same measure also has two sides with the same length, and therefore it is an isosceles triangle. It follows that in a triangle where all angles have the same measure, all three sides have the same length, and such a triangle is therefore equilateral. Triangles are assumed to be two-dimensional plane figures, unless the context provides otherwise (see Non-planar triangles, below). In rigorous treatments, a triangle is therefore called a "2-simplex" (see also Polytope). Elementary facts about triangles were presented by Euclid in books 1–4
