The triangle inequality theorem states that in a triangle, you can pick any two sides’ measures, and when you add them together, the sum will be greater than the measure of the third side. This theorem can be a great importance in construction working. If a construction worker is trying to construct something with a triangle shape, and wants to know if the three measures will make a triangle, then the worker can use the triangle inequality theorem to add the measures together, and see if they will work.  For example, if you had a measurement of 3, 10, and 8 then add them together, 13>8, 18>3, and 11>10.  Therefore, the three measurements can make a triangle.

You can use points of concurrency in triangles for many jobs.  One job is archaeology.  An archaeologist’s job has a lot to do with culture, and the way people used to live.  Archaeologists dig up ancient artifacts, many of which are broken.  To piece these back together perfectly, they can use points of concurrency.  When they use points of concurrency, they find the centers, (centroid, orthocenter, etc.) take each piece, and try to figure out exactly where it belongs in the broken object.  This is just one of the many different jobs that you can use with points of concurrency.
