After doing this Your work should look like this
We start with a triangle PQR. First, we draw the median of the triangle through R
1.  Construct the bisector of the line segment PQ. Label the midpoint of the line S.

See Constructing a perpendicular bisector of a line segment 2.  Draw the median from the midpoint S to the opposite vertex R Next, we draw the second median of the triangle through P
3.  In the same manner, construct T, the midpoint of the line segment QR. See Constructing a perpendicular bisector of a line segment 4.  Draw the median from the midpoint T to the opposite vertex P (Optional step) Repeat for the third side. This will convince you that the three medians do in fact intersect at a single point. But two are enough to find that point.
5.  Done. The point C where the two medians intersect is the centroid of the triangle PQR.
