The point A1 divides the segment BC in ratio 1:n.
When n=1 the segment between the points A and A1 is called a median. There are three medians in a triangle; use vectors to show that the three medians always intersect at one point, even if the triangle is not equilateral. The point of intersection is the centre of mass.
