About Geometria Geometria is a standalone JavaTM application in solid geometry developed and distributed by GeoCentral. Unlike Java applets, standalone applications do not need a Web browser such as Mozilla, Internet Explorer or Safari. MS Windows users run Geometria by simply clicking on a file icon, much like any Windows program. JRE To run Geometria, though, you will need the Java Runtime Environment (JRE) installed on your computer. JRE 1.1.8 for Windows is part of the downloaded Geometria package. System requirements Pentium PC with Windows 95/98/2000/NT/XP or Linux.
