 The trilinear coordinates of a point are the perpendicular distances from the origin to the three lines, drawn through the point, parallel to the sides of the triangle. A coordinate is negative if the associated line lies between the origin and the related...  Classical Electrodynamicsby Julian Schwinger, Lester L.

...coordinates is placed at the intersection of the three perpendiculars from each vertex to the opposite side, the trilinear coordinates of a point are the perpendicular...parallel to the sides of the triangle. A coordinate is considered negative if the line lies between the origin and the corresponding side; thus, the equations... | |
