Two Vertices of a triangle ABC are given by A(6,4) and B(-2,2), and its centroid is G(3,4). Find coordinates of the third vertex C of Triangle ABC.
Given: The coordinates of two vertices of a triangle ABC are A(6, 4), B(-2, 2) and the coordinates of the centroid is
G(3,4).
Let the coordinate of the third vertex of the triangle be C(x, y).
⇒ Coordinates of G =
⇒ 4+x = 9 and 6 + y = 12
⇒ x = 9 - 4 = 5 and y = 12 - 6 =6
Hence, the required coordinate of the third vertex of the triangle is C(5, 6).
