Points d, e, and f are not in a line. to construct a circle through points d, e, and f, begin by drawing line segments ("de" ) ̅ and ("ef" ) ̅. then construct the perpendicular bisectors of ("de" ) ̅ and ("ef" ) ̅, and name the point of intersection of the perpendicular bisectors o. how do you know that point o is the center of the circle that passes through the three points?

a centroid in a triangle, is the point where all the medians meet.

now a peculiar thing about the centroid is that, it cuts all medians in a 2:1 ratio.

so, if that's true, then the median AE, is being cut in two segments AD and DE and AD : DE are on a 2 : 1 ratio, are they?  let's check.
