Behind the numbers

How this calculation works

Locate a point as a convex combination of the vertices of a triangle with base on the x-axis.

THE FORMULAP = αA + βB + (1−α−β)C

A worked example

With vertices (0,0), (6,0), (0,9) and equal weights, the point is (2,3).

Good to know

Weights must be nonnegative and sum to one.
