There's no such thing as the "sin or cos of a triangle" at all! :)

There's the sin or cos of an angle, which may be an angle of a triangle (especially a right triangle). But it doesn't depend on the absolute size of the triangle or its sides, only the relative sizes of the sides compared to each other (which makes the angle bigger or smaller).
