PYTHAGOREAN THEOREM

A2 + B2 = C2

 NOTE DIAGRAM BELOW:
 A2 + B2 = C2
16 + 9  = 25

              Alterations of Pythagorean Theorem

    C2 - B2 = A2
    25 - 9  = 16

    C2 - A2 = B2
    25 - 16 = 9

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)
