In triangle TUV it shows all three medians, segments from a vertex of an angle to the midpoint of its opposite side, intersecting. If constructed correctly, all three medians will intersect in one point, point W. This intersection point can be referred to as the centroid.
For future references:
The circumcenter is the point where all three perpendicular bisectors meet
The orthocenter is the point where all three altitudes meet
The incenter is the point where all three angle bisectors meet
Hope this helps!
