SOH - CAH - TOA
The sine, cosine, and tangent are all trigonometric ratios. A helpful mnemonic for remembering which sides each of these ratios compare is SOH - CAH - TOA
SOH - sine is opposite over hypotenuse
\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}
CAH - cosine is adjacent over hypotenuse
\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}
TOA - tangent is opposite over adjacent
\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}
