A triangle having a vertex as `(1,2)` has mid-point of sides passig from this vertex as `(-1,1)` and `(2,3)` thent he centroid of the triangle is

21.If a vertex of a triangle is (1,1) and the midpoints of two sides of the triangle through this vertex are (-1,2) and (3,2), then the centroid of the triangle is

A triangle has vertex at (1,2) and the midpoints of the two sides through it are (-1,1) and (2,3). Then the centroid of this triangle is (1/3,1) (1/3,2) (1,7/3) (1/3,5/3)

If the vertex of a triangle is (1,1) and the mid-points of two sides therough this vertex are (-1, 2) and(3,2) then the centroid of the triangle is-

If a vertex of a triangle is (1, 1) and the mid-points of two sides through this vertex are (-1, 2) and (3, 2), then the centroid of the triangle is :
