Question

Find the co-ordinates of the centroid of the triangle formed by the following sets of three points: (i) (7, 5), (- 2, 5) and (4, 6) (ii) (4, - 1), (0, 3) and (- 4, - 2) (iii) (3, - 4), (4, 7) and (2, 9)​

Answer 1

Answer:

Centroid=(x1 +X2+X3 /3) , (y1+y2+y3/3)

Step-by-step explanation:

(I) (7+ (-2)+ 4/3) , (5+ 5+ 6/3) =(3, 16/3)

(ii) (4+ 0+ (-4))/3 , (-1 + 3+ (-2)/3) = (0, 0)

(iii) (3+ 4+ 2)/3 ,(-4+ 7+ 9)/3 = (3, 4)
