IMO, I think high school students are certainly capable of exploring
properties of triangles that they could discover the ratios of
opposite:hypotenuse, etc. via their explorations. The teacher would, of
course, want to make sure students know the terminology (i.e. sine, cosine,
tangent) we give to these ratios.

BTW, odd irrelevant stories can be wonderful, but I think adults need them
just as much as kids...
