Given any subspace U of W over K, then the span <U> over L is
a subspace of V over L with dim_{K}U=dim_{L}<U>,
and
In this sense, we may think of one- or two-dimensional K-subspaces of W
as special one- or two-dimensional L-subspaces of V, respectively. Then
the projective plane PG(W) becomes
a subplane of PG(V).

In fact, all subplanes of PG(V) arise in this way.
