If

\vec{a}, \vec{b}, \vec{c}

and

\vec{d}

are distinct vectors such that

\vec{a} \times \vec{c} = \vec{b} \times \vec{d}

and

\vec{a} \times \vec{b} = \vec{c} \times \vec{d} .

Prove that

(\vec{a} - \vec{d}) . (\vec{b} - \vec{c}) \neq 0 i . e . \vec{a} . \vec{b} + \vec{d} . \vec{c} \neq \vec{d} . \vec{b} + \vec{a} . \vec{c}
