    first of all, no offense but you should of learned this in 6th grade.

    second of all, you do not need the Pythagorean theorem to calculate the dimensions of stairs, you need to calculate the rise and run if each tread. a good rule of thumb is 7" rise, 11" run (for each tread, (assuming imperial) divide the finish floor to finish floor height by 7 to find the number of risers, the stair well length by 11 (minus space for landings) to find the number of treads, draw it out on graph paper (or even sketch up)

    there is the length of your stringer.

    i use to do this for a living, trust me on it.
