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)
