Vertex angle the sum of the interior angles is π("n" − 2) radians or 180("n" − 2) degrees. Because more than two lines in a polytope can intersect in the same space, the number of vertex angles from any given vertex is not always one. Because of this, it is sometimes necessary to specify not only the vertex, but also the specific line segments that make up the angle. Vertex angle In geometry, a vertex angle is an angle associated with a vertex of an n-dimensional polytope. Often a vertex angle of a polygon is referred to simply as an angle of
180 Degrees South: Conquerors of the Useless of so many ecological horror documentaries on topics ranging from global warming to the corn syrup in our peanut butter." He writes "The regard for the planet shown in "180° South" comes from the quiet, philosophical nature of the people profiled in the film, who realize there is more adventure in the preservation of nature than in its conquering." "Minneapolis Star-Tribune" praised the film by writing "If you are this close to chucking it all in, packing your bags and going vagabond, by all means do not see "180° South." Director Chris Malloy's eco-tourist documentary could stoke your wanderlust to
