Parallel projection area and Holditch’s theorem

In this paper, the parallel projection area of a closed spatial curve formed under the motion B(Cj) defined along the closed spherical curve c^ [12] have been calculated. After that Holditch’s Theorem [7] and its some corollaries which is well-known [3] have been generalized to closed spatial curve.
