$ \displaystyle \frac{\pi}{2} \text{radians} = 90^{\circ}$
$ \displaystyle \sin(A) = \frac{opp}{hyp}$
$ \displaystyle \cos(A) = \frac{adj}{hyp}$
$ \displaystyle \tan(A) = \frac{opp}{adj}$
$ \displaystyle \sin(B) = \frac{adj}{hyp}$
$ \displaystyle \cos(B) = \frac{opp}{hyp}$
$ \displaystyle \tan(B) = \frac{adj}{opp}$
