Soh cah toa
Sin = opposite/hypotenuse
Cos = adjacent/hypotenuse
Tan = opposite/adjacent
If you have, for example, a 3/4/5 right triangle, you know that the angle
between the 3 and 5 legs is:
arcsin(4/5)
because the sine of the angle is 4/5.
Geez, this is hard without diagrams! Hope that made sense.

: Subject: Geometry Question
:
:
: I didn't pay attention in junior high and now have a question about
: geometry. Anyone on the list know the answer?
:
: I have a right triangle and know the size of the legs (and thus
: the size of
: the hypotenuse). Now I want to calculate the size of the angles other than
: the right one, and to write a simple formula to do this.
:
: Anyone know how? I realize the size of both of the angles is equal to 90
: degrees, and that the size of the angles is directly proportional to the
: size of the legs at which they point.
:
: An expression of this would be:
:
: For triangle ABC with hypotenuse z, where B is a right angle, where BC = x
: and AB = y, A = ???
