Question

Coordinate Geometry: Find the coordinates of the centroid of each triangle with the given vertices. X(5,7), Y(9, -3), Z(13,2). Show your Work

Answer 1

Given the coordinates of the three vertices of a triangle ABC, 
the centroid O coordinates are given by : 

Ox=Ax+Bx+Cx/3
    = 5+9+13/3
    = 9 
Oy=Ay+By+Cy/3
    = 7-3+2/3
    = 2
