Find the sine, cosine, and tangent of each angle using the unit circle.
$\theta =225°,(-\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2})$

$\sin \theta =-\frac{\sqrt{2}}{2},\cos \theta =-\frac{\sqrt{2}}{2},\tan \theta =2$

$\sin \theta =\frac{\sqrt{2}}{2},\cos \theta =-\frac{\sqrt{2}}{2},\tan \theta =-1$

$\sin \theta =-\frac{\sqrt{2}}{2},\cos \theta =-\frac{\sqrt{2}}{2},\tan \theta =1$

$\(\sin\]\theta\)=\(\frac{\sqrt2}{2}\),\(\cos\[\theta\)=\(\frac{\sqrt2}{2}\),\(\tan\]\theta\)=\(\frac{\sqrt2}{1}\)$
