This study is devoted to discuss the special cases that occur in linear programming problems (LPP). We have discussed each of them with three aspects. The aspect represents the algebraic base that has been shown with help of POM-QM software, and TORA software, the second one focuses on the geometric representations of three-dimensional space, the third aspect deals with the economic and administrative meaning. These ideas have been shown in geometrical meanings of three dimensional space by using the MAPL software.
