Let \(G\) be a finite group and let \(k\) be a field. We say that a \(k G\)-module \(V\) has a quadratic geometry or is of quadratic type if there exists a non-degenerate (equivalently non-singular) \(G\)-invariant quadratic form on \(V\). If \(V\) is irreducible or projective indecomposable and \(k
