Hip truss systems are very popular throughout the country. In this design each side of the building has a roof pitch and eave. To frame this style roof, hip trusses are utilized from the main peak of the building, stepping down with a flat top chord. The flat portion is increased the nearer the truss is to the end wall.

Step 3: Using Trigonometry. To calculate forces on a truss you will need to use trigonometry of a right triangle. A right triangle is a triangle in which one angle is equal to 90 degrees.
