$$
\tan(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}\
\sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}
$$

Hypotenuse is the edge of a _right_ angle triangle which is opposite to the right angle.  Opposite edge is the edge opposite to the angle (duh!) which the trigonometric function is calculated.  The two angles in a right triangle have different opposite edge.  For example, the opposite edge of angle B is AC and the opposite edge of A is CB.  The opposite edge of C is AB.  As C is the right angle, AB is the hypotenuse.
