“Conics in Projective Geometry”

Judith Silver

Marshall University

Abstract

The definition of a conic usually requires the concept of distance; but in projective geometry, conics are determined in a metric-free way. This talk will show how such conics are formed, using Geometer's Sketchpad and some audience participation. All of the material should be accessible to students, as well as faculty.
