When framing a house,
trigonometry is
extremely important to
ensure that you are
getting all your
measurements correct.
You need
measurements of angles
and lengths to ensure
that the house is built
straight and within
appropriate
specifications. Without
accurate measurements
and calculations houses
can be unstable and
