1. Create the midpoint of each side of the triangle.[br][br]2. Create a line segment from each vertex to the midpoint of the opposite side of the triangle.[br] This segment is called the median.[br][br]3. You should note that all of these line segments intersect at a single point. Label this point O.[br]This point is called the centroid of the triangle.[br][br]4. Use the distance tool to measure the length of the segments from the centroid to the midpoint and from the centroid to the vertex.
