👉 In algebraic geometry, the term "coadjacence" refers to a property of geometric objects that is related to their relationships with each other. Specifically, in projective geometry, coadjacence means that two lines are coplanar if they do not meet at any point. For example, consider two lines \(L_1\) and \(L_2\) in the plane, where \(L_1\) lies above \(L_2\), and let \(M\) be
