L.E.G.O. - AN INTERACTIVE GRAPHICS SYSTEM FOR TEACHING GEOMETRY AND COMPUTER GRAPHICS

L.E.G.O. is an interactive graphics system for creating, viewing and manipulating two-dimensional geometric figures and three-dimensional objects. The fundamental operations of the L.E.G.O. language form an electronic metaphor of geometric constructions with a straightedge and compass. This is consistent with the primary application of L.E.G.O.,
