Conics

Conics

The parabola, ellipse, and hyperbola are three kinds of conic section, obtained by slicing a cone with a plane. They have many well known properties and constructions, and many of these are illustrated in 3D-XplorMath. They have interesting “robustness properties”, such as invariance under orthogonal projection.
