In which figure is point G a centroid?

Triangle A B C is a right triangle. Lines are drawn from each point to the opposite side and intersect at point G.
Triangle F D E is shown. Lines are drawn from each point to the opposite side and intersect at point G. Each line segment splits each side into 2 equal parts.
Triangle L M N is shown. Lines are drawn from each point to the opposite side and intersect at point G. Each angle has a different measure.
Triangle H J K is shown. Lines are drawn from each point to the opposite side to form right angles and they intersect at point G.
