Question

Find the centroid of the triangle whose vertices are:
(i) (1, 4), (-1, -1), (3, -2)
(ii) (- 2, 3), (2, -1), (4, 0)

Answer 1

Step-by-step explanation:

1)let x1=1,y=4,x2=-1,y2=-1,x3=3,y3=-2

by centroid formula

x=x1+x2+x3/3

=1-1+3/3=1

x=1

y=y1+y2+y3/3

=4-1-2/3

=1/3

x=1,y=1/3

mark me as brainliest

Answer 2

Answer:

x=1 , y=1/3

Step-by-step explanation:

by centroid formula

x1 + x+ x3

x= --------------------- y= y1 + y2 + y3

3 --------------------

3

x= 1 + (-1) + 3 y= 4 + (-1) + (-2)

------------------------

3 y= 1

x= 3 --------

------- 3

3

x=1 y= 3
