sentences:  Let "K" be a convex body in "n"-dimensional Euclidean space R"n" containing the origin in its interior.Let "S" be an ("n" − 2)-dimensional linear subspace of R"n".For each unit vector "θ" in "S"⊥, the orthogonal complement of "S", let "S""θ" denote the ("n" − 1)-dimensional hyperplane containing "θ" and "S".
