**(i) Median AD of the triangle will divide the side BC in two equals parts. So D is themidpoint of side B.**

**Coordinates of D**

**(ii) Point P divides the side AD in a ratio 2:1**

**Coordinates of P**

**(iii) Median BE of the triangle will divide the side AC in two equal parts. So E is the midpoint of side AC.**

Point Q divides the side BE in a ratio 2:1

Median CF of the triangle will divide the side AB in two equal parts. So F is the midpoint of side AB.

**(iv) Now we may observe that coordinates of point P, Q, R are same. So, all these are representing same point on the plane i.e. centroid of the triangle.**
