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
Options
A.

B.

C.

D.

Solution

Vertex of triangle is (1, 1) and midpoint of sides
through this vertex is (-1, 2) and (3, 2)
⇒ vertex B and C come out to be
(-3, 3) and (5, 3)
∴ centroid is

⇒ (1, 7/3)
