 Description  
 Centroid:  The point of intersection of the medians of a triangle. Also, the point in a figure or solid which is the balance point, or center of gravity, of the figure or solid.




The medians of a triangle intersect at a point called the centroid. If you were to cut out this triangle and try to balance it on a pencil point, the balance point is the same as the centroid.

Can the centroid ever lie outside the triangle? Why or why not?
