(1) If two vectors are linearly independent, then they areorthogonal.

(2) If x is orthogonal to both u and v, then x must beorthogonal to u − v.

(3) If W is a subspace of Rn, then W and W^⊥(Wtranspose) have no vectors in common.

(4) If z is orthogonal to v1 and v2 and ifW =span(v1,v2), the z must be in W^⊥​​​​​​​(Wtranspose) .

(5) ∥cv∥ = c∥v∥ for all scalars c and vectors v in Rn.
