Students took the Similarity test (chapter 11) on Friday. This week we have learned the right-triangle definition of the trigonometric functions sine, cosine and tangent. As of now these functions take as input one of the *non-right* angles in a right triangle and their output is a specific ratio of sides in *all such similar right triangles*.

So, based on this definition, if that means that in any right triangle with a angle, the ratio of * *is approximately .57*.* In the figure below this means that *.*
