The points `A(x_(1), y_(1)) , B(x_(2), y_(2)) and C(x_(3), y_(3))` are the vertices of `Delta ABC ` and AD is a median in `Delta ABC ` . Find the coordinates of a point G on median AD such that AG : GD = 2 : 1

Text Solution

Verified by Experts

The correct Answer is:
`((x_(1) + x_(2) + x_(3))/(3),(y_(1) + y_(2) + y_(3))/(3))`
