Defect (geometry)

In geometry, the defect of a vertex of a polyhedron is the amount by which the sum of the angles at the vertex falls short of a full circle. If the sum of the angles exceeds a full circle, as occurs in some vertices of most (not all) non-convex polyhedra, then the defect is negative. If a polyhedron is convex, then the defects of all of its vertices are positive.
