Geometry is the branch of mathematics used to measure a
wide variety of objects, including triangles, squares, rectangles and
circles. If you have worked in construction as long as I have, you
definitely ran into at least one situation that required a geometric
formula to aid you, in the construction process of at least one
building.

Think of it like this, most of the rooms in your
house, office, shopping malls and other buildings are rectanglar. Each
one of the corners of these rooms usually has a 90° angle and definitely
fits into our description of geometry.
One of the best formulas I've ever used as a carpenter, stair builder
and even as a contractor, was the Pythagorean Theorem. Remember, most of
the buildings constructed today are created from squares, rectangles and
triangles.
The Pythagorean
Theorem can be used to figure out the lengths of roof rafters, stair
stringers and can even be used to square buildings.
I can't remember one time I ever needed to use algebra, calculus or
statistical probability, when building a house, but geometry is a must
and any stair builder or house framing carpenter should understand that,
"A squared plus B squared equals C squared."
