The Pythagorean Theorem
The Pythagorean Theorem is one of the oldest, most
well-known, and widely used mathematical relationship in
history. It has been a fundamental part of math classes everywhere around the
world for several thousand years.
First described by the Greek mathematician Pythagoras 2500 years ago, the Pythagorean
Theorem describes the
relationship between the three sides of a right triangle.
This theorem can be very useful in the construction trade, especially roofing.
Many times certain measurements on
a roof are difficult to take manually due to factors such as height, pitch or
the condition of the roof itself. The
following example will illustrate the fundamentals of how the theorem works.
The subsequent pages will give
many examples of how to use the theorem in real situations.
