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.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
