Calculate total length
- In the last video, I showed you the Pythagorean Theorem that allows us to calculate the length of the third side of a triangle if you know the lengths of the other two sides. Now, for those of you that might still be thinking, "Okay, but when will I need to use this?" Let's look at some examples. There are actually quite few instances where this comes in handy in construction, because we tend to work off of two-dimensional drawings, or blueprints. So when we're looking at the plan view of a roof, if you simply measure the roof from the peak to the edge, you're really measuring the run, not the actual length of that roof. Let's do the math on a couple of examples. On this house, there's a new sewer line that will need to be installed.
