The notion of rectilinear k-simplex appears in Theorem 10.27 of Rudin's book "Principles of Mathematical analysis", then what is the definition of a rectilinear k-simplex? I read the proof of Theorem 10.27 and think that the proof treats oriented affine k-simplex instead of rectilinear k-simplex, is it right?
