$\noindent To prove this result, take the tan of both sides and show they are equal (use trig. identity for R.H.S.: $\tan (\pi -\alpha )=-\tan \alpha$. Use compound angle formula for L.H.S. and the fact that $\tan \frac{3\pi}{4} = -1$.). Then show that both the L.H.S. and R.H.S. lie in the same branch of the tan graph.$
