It is *freeware*, so you don't need to pay for it. It allows the construction of dynamic geometric figure. It's an educational oriented software. So we took care of the design of the Dr GEO user interface. It use intensively the mouse and allow advanced features as contextual menu and textual feedback of geometrical element under the mouse pointer. Using Dr GEO, the feeling is very good. We experiment it with student from eleven year old. They master the interface very quickly. Also Dr GEO can handle differents nationals languages as Chinese, English, French and Spanish (More can be add). This software can be used by mathematic teachers. In a class room to make a show or in a computer class room. Dr GEO can be use by students helping them to resolve geometric home exercices. Also, geometry lover will enjoy Dr Geo To use Dr Geo, you need: 1. A 486DX or better. Dr Geo makes a lot of floatting point calculs so an arithmetic coprocessor is required. 2. Dos, Windows 3.11 or Windows 95. 3. A Microsoft compatible mouse. 4. A 32 bits super VGA video card or better.

ADVANCED & I/O FIELD : - an intuitive graphic user interface , Appear When Needed. - a powerfull macro construction feature with unlimited input & output geometry objects arguments. - load and save functions for the construction figure and the macro-construction. - save function in PCX bitmap format. - menu to change the geometry objects rendering. - menu to change the screen display. - an Open Language Technology (OLTech) allowing the use of alphabets & ideograms systems in any national language operating system (Dos or Window). - ability to switch, from Dr Geo, in differents languages as Chinese, English, French & Spanish. More can be add as Korean, Japanese or other alphabet language. -- ________________________________________ Hilaire Fernandes hilaire DOT fernandes AT iname DOT com http://xoom.com/FeYiLai
