Is This Tool Helpful?


Ratios of directed line segments calculator is an online tool that finds the point coordinates dividing the line (internally/externally) joining two points A and B for a given ratio m and n.

Coordinates of a point - Definition

Coordinates of a point are a pair of numbers that state its precise location on a two-dimensional plane. The coordinate plane has two axes at right angles to each other, called the x and y axis.

x1, x2, y1, y2 are end point of a line segment,

m and n are external and internal ratios.

How to find ratio of a directed line segment?

Let’s find out coordinates of points dividing a line segment joining two points with an example.


Find the point coordinates that divides a directed line segment internally having endpoints (2, 4), (3, 6) with a ratio of 5:6.


Step 1: Identify the values.

x1 = 2, x2 = 3, y1 = 4, y2 = 6, m = 3, n = 1

Step 2: Place the values in equation of internal ratio of directed line segment.

= (mx2+nx1/m+n, my2+ny1/m+n)

= (3×3+1×2/3+1, 3×6+1×4/3+1)

= (11/4, 22/4)

Hence, the points (11/4, 22/4) divides the line joining points (2, 4), (3, 6) with a ratio of 5:6.

Use external ratio segment formula for external points coordinates or use our line segment ratio (partition) calculator above to automate your calculations.
