SUMMARY
The intersection of two subspaces H and K of a vector space V, denoted as K ∩ H, is indeed a subspace of V. This conclusion is established by verifying that K ∩ H satisfies the three criteria for a subspace: it contains the zero vector, is closed under vector addition, and is closed under scalar multiplication. These properties stem from the definitions of subspaces and the axioms of vector spaces.
