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
Less than Angels with an air of detachment. Anne Wyatt-Brown writes that "Catherine represents Pym’s view of the world. She shares her author’s imagination, her amused reaction to anthropologists, and her detachment." Less than Angels Less Than Angels is a novel by Barbara Pym, first published in 1955. The novel is largely concerned with the activities of a group of anthropologists, and is to some extent based on the author's own experiences working at the International African Institute in London.
