Question

If two vertices of a triangle are (-3, 1), (0, -2) and centroid is at origin, then find the coordinates of the third vertex?

Answer 1

Answer:

(3,1)

Step-by-step explanation:

let the 3rd vertex be (x,y) and other two vertices are (-3,1) and(0,-2)

coordinates of centroid of triangle =(0,0)

therefore,

(-3+0+×/3 , 1-2+y/3) =(0,0)

-3+x/3=0

x-3=0

x=3

and 1-2+y/3 =0

y-1/3=0

y-1=0

y=1

therefore,

x=3 and y=1
