This article mentions some fundamental concepts and crucial results of linear algebra as well as linear combination, linear span, linear dependence, etc. in vector space and how to use them as an effective tool to determine “the incidence” to affirm the relationships between m-planes in projective space in projective geometry. | Applying linear relationships in vector spaces applying linear relationships in vector spaces to solve the problem class about incidence to solve the problem class about incidence in projective space
