Utilizing a maximal flag construction and its intersection with the hyperplane , we define a hierarchical membership function based on fuzzy set theory. Each point of PG(5,2) is assigned a degree of membership in [0,1] according to its level in the flag, satisfying ​. Through this framework, we analyze three alpha planes and three beta planes passing through the base point , classifying them by their fuzzy equivalence. It is shown that two alpha planes are fuzzy equivalent, while the beta planes are distinguished by the fuzzy degrees of the lines they share with the base plane. This approach bridges combinatorial projective geometry and fuzzy logic, enriching the geometric understanding of the Klein correspondence through fuzzification.}, number={2}, publisher={Eskişehir Teknik Üniversitesi}
