We set the roof trusses on our office expansion project. The roof has a single slope to match the slope on the existing building and the trusses run the full width of the building. I like to see the patterns that trusses create. I always think back to my 10th grade geometry teacher as I see all the right triangles. He made sure we understood the strength that triangles impart to their structure. At one time we made various models from toothpicks and measured how much weight the model would hold. Now hear I am about 45 years later using triangles in my daily construction activities.
