Gossard's perspector and projective consequences,
Forum Geometricorum, 13 (2013) 169--184.
Abstract. Considering as starting point a geometric configuration studied, among others, by Gossard, we pursue the projective study of a triangle in the Euclidean plane, its Euler line and its nine-point circle, and we relate Pappus' Theorem to the nine-point circle and Euler line.
