Pythagorean Theorem
PYTHAGOREAN THEOREM A 2  + B 2   NOTE DIAGRAM BELOW: A 2  + B 2  = C 2 16 + 9 = 25    Alterations of Pythagorean Theorem     C 2  - B 2  = A 2     25 - 9  = 16     C 2  - A 2  = B 2     25 - 16 = 9 SEE THE RELATION !! In   Carpentry   they   use   what   is   called   a   3,4,5   triangle   (or multiples    of    3,4,5    i.e.    9,12,15)    to    produce    right    angles accurately.   If   you   construct   a   line   3   inches   long   and   hinge another   line   off   of   it   that   is   4   inches   long   and      then   connect the   ends   with   a   5   inch   line   it   will   produce   a   right   angle triangle.   This   will   help   us   to   understand   the   Pythagorean Theorem. (Theorem is a statement which requires proof)
