Question

R 36. Find out the third vertex of the triangle if, Vertex - 1 = (8,6) Vertex - 2 = (-2, 6) Centroid = (8,4) Ops: A. O(10-2) B. O(10, 2) CO(18,0) D. (20,-2)​

Answer 1

Answer:

Step-by-step explanation:

Let the third vertex of the triangle be C(x,y) and the other vertices A(-3,1) and B(0,-2).

Coordinates of the centroid of the triangle = (0,0)

∴ (-3+0+x / 3, 1-2+y / 3) = (0,0)

-3+x = 0

x = 3

And - 1 + y = 0

y = 1

∴ The third vertex of the triangle is (3,1)
