Which trig ratio is opposite over hypotenuse?

Explanation:
In a right triangle, the sine of an angle is defined as the length of the side opposite the angle divided by the length of the hypotenuse. This makes the ratio opposite over hypotenuse exactly the sine of the angle. The other standard ratios are different: cosine uses adjacent over hypotenuse, tangent uses opposite over adjacent, and cotangent uses adjacent over opposite. So the ratio that corresponds to opposite over hypotenuse is sine.
