Dividing the line segment AB into ratio 1:3 or 3:1 means dividing the line segment into four equal lengths, as shown in the diagram below.
Point P is the point that divides the line into 1 part and 3 parts, from A.
Point Q is the point that divides the line into 1 part and 3 parts, from B
Hence, P and Q are points on different position
