Welcome to Wilson Stothers' Cabri Geometry and Conics Pages
These pages were written to accompany a course in Geometry at the University of Glasgow, but they are also relevant to the Geometry Block in the Open University M203 course.- The Geometry Page gives a purely geometric treatment of conics,
poles, polars and duality. The treatment of duality is thorough.
The later Theorems go beyond M203, so should be treated as enrichment material. - The Algebra Page gives a purely algebraic treatment of the same topics.
The approach is rather different from M203 - it uses the matrix formulation extensively,
and treats Joachimsthal solely in homogeneous coordinates
Again it goes beyond M203. - The Classical Theorems Pages illustrate eight theorems you will meet in M203,
and try to explain how they are related, especially by duality. - The Conics Menu Page is for those with access to the Cabri Geometry package.
Information about Cabri, and a chance to download a demo version appears on the
Introduction Page.
