Question

find the third vertex of a triangle abc if two of it's vertices are b(-3,1) and c(0,-2) and it's centroid is at the origin​

Answer 1

Answer:

Let the third vertex of triangle be (x,y).

Step-by-step explanation:

Now,

0=-3+0+x/2

then x=3

Similarly for y

0=1-2+y/2

then y=1

Therefore third vertex is (3,1)
