I am looking for the \"rules\" or \"formula\" or \"whatever\" that makes this a correct statement.  You have a triangle with a right angle.  Side A =3ft Side B=4ft  (side A and B are connected by the right angle).  We know that side C (the hypotonus) =5ft.  I want this equation in a larger term (ie Side A=10ft Side B=20ft what is side C)  Thanks so much for your help!  I actually miss doing this on a regular basis!  I loved math in high school, and now it just helping my dad build a cabin.  Thanks again.  Michelle Wagner </SPAN>\n" );
