It is not a triangle center , but has trilinear coordinates (Kimberling 1998, p. 47). Note that extreme care is needed when consulting the literature , since reversing the order in which the points of the triangle are labeled results in exchanging the Brocard points. The second Brocard point is the interior point (also denoted or ) for which the angles , and are equal, with the unique such angle denoted .

Such a path might result from a fox pursuing a rabbit or a missile seeking a moving target. This set of superimposed "snapshots" shows the lines of sight at regular intervals of four "bugs" chasing one another, all moving at the same speed after starting at the corners of a square. Courtesy of John Sharp. More formally, a pursuer must always head directly toward the pursued, and the pursuer's speed must be proportional to or match that of the pursued. Plotting the lines of sight at regular intervals and tracing out the corresponding paths can produce fascinating patterns. Pursuit curves can arise in a variety of situations and may involve more than one pursuer. Suppose that a person stands at each corner of a square traced out on the ground. Each person looks directly at the person to his or her left, then begins to walk toward that person. If all four people move at the same time and at the same constant speed, each person follows a spiral path toward the square's center. The following recipe for drawing pursuit curves works with squares and other regular polygons: The first two steps in drawing pursuit curves based on a square.
