Abstract

This paper explores a geometrical way to sketch graphs of the general quadratic in two variables with Geometer's Sketchpad. To do this, a geometric procedure as described by De Temple is used, bearing in mind that this general quadratic Equationequation (1) represents all the possible conics (conics sections), and the fact that five points (no three of which are collinear) uniquely determine a conic.
