Hello Frodo,

     If a turle is located at xcor = 3 and ycor = 4 and started at the 
usual location (0,0) and moved forward to get to (3,4), how far did it 
move fd forward?

     hyp length squared = adjacent leg squared + opposite leg squared

      5 squared = 3 squared + 4 squared

     25 = 9 + 16

     The length of the hypotenuse is the square root of the
     sum of the squares of the lengths of the two legs,

     ie 3 squared plus 4 squared = 25 and the

        square root of 25 is 5.

    For the classic example of a 3 by 4 by 6 right triangle!!!!!

Sample problem for Pythagorean theorem practice:

If a turtle is located at 10.4616 for the xcor
                    and at  3.3992 for the ycor,

     ie it is at (10.46, 3.34) then HOW FAR is it from (0, 0)?

     How long is the hypotenuse, basically, if it went from
     (0, 0) to (10,46, 3.34) with its PEN DOWN PD when it went fd forward?

     Use those two LEGS!!!

    2    2     2
   3  + 4  =  5
