The square on the hypotenuse is equal to the sum of the squares on the other two sides.
Is that what you meant?
Or,
did you meant SOHCAHTOH
which stands for sine=opp/hyp, cos=adj/hyp, tan=opp/adj
Or
did you mean 'some old hags can't always hide their old age"
where the first letters stand for sine=opp/hyp, cos=adj/hyp, tan=opp/adj
Or did you mean something else?
