Pedal Surfaces of First Order Congruences

Sonja Gorjanc ; Faculty of Civil Engineering, University of Zagreb, Zagreb, Croatia

Abstract

This paper is an overview of the pedal surfaces {P_n}^{n+2} for
first order line congruences. We describe their construction, prove their algebraic properties, derive parametric and implicit equations and visualize these new resulting surfaces with the program Mathematica in seven examples.

Keywords

congruence of lines; pedal surface of congruence; pinch-point; singular point
