		Isomorphism Examining the idea of isomorphism in group theory, this program shows how two groups may really be the same, even though they look totally different at first sight. Produced by the Open University. (25 minutes)(more details)		DVD $99.95
		Conics in Perspective All conic sections can be found as slices of some cone and are therefore perspectively equivalent. In this program, this result is used to prove an interesting theorem in two-dimensional geometry. Produced by the Open University. (25 minutes)(more details)		DVD $99.95
		Symmetry Counts This program introduces the idea of symmetry of three-dimensional objects, including a review of the symmetry of two-dimensional figures. Produced by the Open University. (25 minutes)(more details)		DVD $99.95
		Perspectives This program explores how the use of perspective to draw diagrams in apparently different ways can help mathematicians to prove important results in plane geometry. Produced by the Open University. (25 minutes)(more details)		DVD $99.95
		Inversive Geometry An introduction to the idea of inversive geometry, this program demonstrates how inversive geometry can be used to study the geometry of circles. Produced by the Open University. (25 minutes)(more details)		DVD $99.95
