Barycentric coordinates are triples of numbers corresponding to masses placed at the vertices of a reference triangle. These masses then determine a pointwhich is the geometric centroid of the three masses and is identified with coordinates. The vertices of the triangle are given by, and. To find the barycentric coordinates for an arbitrary pointfind and from the point at the intersection of the line with the sideand then determine as the mass at that will balance a barycentriqud atthus making the centroid left figure.

### Interpolating in a Triangle – Code Plea

Furthermore, the areas of the triangles, and are proportional to the barycentric coordinates, and of right figure; Coxeterp. Barycentric coordinates normalized so that they become the actual areas of the subtriangles are called homogeneous barycentric coordinates. Barycentric coordinates normalized so that.

Barycentric and areal coordinates can provide particularly elegant proofs of geometric theorems such as Routh’s theoremCeva’s theoremand Menelaus’ theorem Coxeterpp. Not necessarily homogeneous barycentric coordinates for a number of common centers are summarized in the following table.

In the table, and are the side lengths of the triangle and is its semiperimeter. In barycentric coordinates, a line has a linear homogeneous equation.

In particular, the line joining points and has equation. If the vertices of a triangle have barycentric coordinatesthen the area of the triangle is. Mathematics and Astronomy in Nineteenth-Century Germany.
