Ratios of Directed Line Segments Calculator
Find the point dividing a segment in a given ratio (section formula).
The section formula finds the point that divides a segment internally in the ratio m : n.
The math behind it
The dividing point is the weighted average of the endpoints: P = (m·B + n·A) ÷ (m + n).
Worked example
From (0,0) to (10,5) in ratio 2:3 → (4, 2).
FAQ
