bearing in mind that the centroid in a triangle cuts each of the three medians in a 2:1 ratio.
since we know that A C = 12, let's split it in a 2:1 ratio then, cleary from the picture the larger is F C, so F C : A F is on a 2:1 ratio.
Give the quadrant each set of coordinates lies in 1 , 5 -2 , 4 -3 , 2 4 , -4
