All real-world triangles have a single point called the center of mass. This point represents the average position of all of the triangle’s mass. So, in theory, any triangle can balance with a force applied only to its center of mass. A pencil tip, for instance, could hold up a real-world triangle if it were placed directly at the triangle’s center of mass. Consider what you know about the three points of concurrency mentioned above, or conduct outside research, if necessary. One of these triangle centers always occurs at a triangle’s center of mass. Which point of concurrency is it? Explain your reasoning.
