Question

Find the centroid of the (1, 1) (2, 2 ) (- 3, - 3)

Answer 1

let A ( 1,1 ) B ( 2,2 ) nd C ( -3,-3 ) be A ( x1,y1 ) B ( x2,y2 ) nd C ( x3,y3) respectively

now let the centroid be P ( x,y )

P ( x,y ) = { ( x1 + x2 + x3 ) / 3 , ( y1 + y2 + y3 ) / 3 }

on comparing

x = ( x1 + x2 + x3 ) / 3

= { 1 + 2 + (-3) } / 3

= ( 3 - 3 ) / 3

= 0 / 3

= 0

y = ( y1 + y2 + y3 ) / 3

= { 1 + 2 + (-3) } / 3

= ( 3 - 3 ) / 3

= 0 / 3

= 0

Hence the centroid of A ( 1,1 ) B ( 2,2 ) nd C ( -3,-3 ) is P ( 0,0 ).

hope it's helpful to uhhh.....!!!!
