“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.
