In a, b, and c are noncollinear points in R 2 and p is any other point

Question:

In a, b, and c are noncollinear points in R2 and p is any other point in R2. Let Δabc denote the closed triangular region determined by a,b, and c, and let Δpbc be the region determined by p, b, and c. For convenience, assume that a, b, and c are arranged so that image is positive, where a, b, and c are the standard homogeneous forms for the points.


Show that the area of Δabc isimage.
