    Generalization and extension of the Wallace theorem - Gotthard Weise​

    In the Wallace theorem we replace the projection directions (altitudes of the reference triangle) by all permutations of a general direction triple, and regard simultaneously the projections of a point P to each sideline. Introducing a pair of Wallace points and a pair of Wallace triangles, we present their properties and some connections to the Steiner ellipses.
