the trigonometric ratios is talking about the sine ratio the cosine ratio and the tangent ratio and what it's talking about is when we have a right-angled triangle we can use sine cosine and tangent to figure out sometimes an angle within the triangle and sometimes a side of the triangle if we're given enough other pieces of information the trick is to label your sides correctly first off we must always have a right angle to be able to apply this if you have a triangle that's not a right angle like that or like that they kind of look the same if you have a non right angle triangle you can't apply this so that's the first thing you have to check for always opposite your right angle is the longest side along the triangle and the longest side which is opposite that right angle we call the hypotenuse the other two are going to be called the opposite and the adjacent and that'll depend in relationship to which angle we're talking about so say our mystery angle theta for example is down here
