In this paper, we define space-like line congruence and their space-like parameter ruled surfaces R11(t) and R21(t) of R1 3. Then, by choosing space-like parameter ruled surfaces as space-like principle ruled surfaces, we obtain some relations among the magnitudes of space-like ruled surfaces R1(t), R11(t). © TÜBİTAK.eninfo:eu-repo/semantics/closedAccessArticle232333344Q2
