    The Simson-Wallace theorem extension on skew quadrilaterals

  • Original language description

    The well-known Simson-Wallace theorem reads: If P is a point in the circumcircle of a triangle ABC then orthogonal projections of P onto the sides of ABC are collinear. The generalization on skew quadrilaterals in 3D space is as follows: Let K,L,M,N be orthogonal projections of a point P onto the sides AB, BC, CD, AD of a skew quadrilateral ABCD respectively. Then the locus of P such that K,L,M,N are coplanar is a cubic surface H=0. In the paper some relations between a skew quadrilateral ABCD and its associate surface H are studied.
