Centroid of a triangleThe centroid of a triangle is the point where the three medians of a triangle meet or intersect An illustration of the centroid is shown below.  The median is the line that starts from a vertex and goes to the midpoint of the opposite side After you construct all three medians, the point where they intersect ( shown in red ) is the centroid Now, If you put a triangle on the coordinate system, you can easily get the centroid by doing some simple calculation  [( x1 + x2 + x3)/3, (y1 + y2 + y3)/3] Example: Find the centroid of the following triangle with veetices (1,2), (3,4), and (5,0)
