# A triangle has a vertex at (1,2) and the mid points of the two sidesthrough it are (-1,1) and (2,3). Then the centroid of this triangle is : Option 1) $(1,\frac{7}{3})$ Option 2) $(\frac{1}{3},2)$ Option 3) $(\frac{1}{3},1)$ Option 4) $(\frac{1}{3},\frac{5}{3})$

Centroid of triangle = $(\frac{1+3-3}{3},\frac{2+0+4}{3})=(\frac{1}{3},2)$

Option 1)

$(1,\frac{7}{3})$

Option 2)

$(\frac{1}{3},2)$

Option 3)

$(\frac{1}{3},1)$

Option 4)

$(\frac{1}{3},\frac{5}{3})$
