It allows formal deductive reasoning about objects constructed within DGSs. GCLCprover is an ATP based on the area method. The first author of this paper is responsible for the Portuguese version of Eukleides: EukleidesPT is available from

The mirrored version isДЄvailable from EMIS (The European Mathematical Information Service) There are versions of GCLC for Windows and for Linux.Д¦Дћukleides is available from, There are versions for a number of languages. Both tools have graphical user interfaces and produce, in LTEX form, illustrations that correspond to geometric constructions.ДҐ GCLC package is freely available from janicic/gclc/. These descriptions directly reflect meaning of mathematical objects to be presented, and are easily understandable to mathematicians. Hence, in using these tools, producing mathematical illustrations is based on 'describing figures' rather than on 'drawing figures'. They both use declarative languages to specify geometrical constructions. In this section, we give a brief description of the tools that are currently integrated in GeoThms: GeoThms, is a framework that links dynamic geometry software, geometry automatic theorem provers, and a repository of geometry problems providing a common web interface for all these tools (see Figure 1). Section 7 discusses further work, and Section 8 draws final conclusions. Section 2 describe GeoThms components Section 3 presents the structure of the web interface Section 4 is about communication and representation issues Section 5 presents GeoThms through some illustrated examples. Section 6 gives more details about related work. We are not aware of any system that, like GeoThms, gives full, web-based access to DGS, use theorem proving with human-readable proofs generated and provides open repository of geometrical constructions and conjectures. Some of them combine features of DGS and automated theorem provers, some of them have web interfaces, and some of them provide repositories of geometrical theorems. There are several systems related to GeoThms. The web interface is a server-side solution written in PHP, designed to enable GeoThms users to easily browse through the list of geometric problems, their statements, illustrations and proofs, and also to interactively use the drawing and automatic proof tools. GeoThms provides a web workbench that tightly integrates mentioned tools into a single framework for constructive geometry. The ATP used, GCLCprover, is based on the area method, and it produces human readable, synthetic geometrical proofs. The DGSs currently used within GeoThms are GCLC and Eukleides, two widely used dynamic geometry packages. (DGS), Automatic Theorem Provers (ATP), and GeoDB, a database of geometrical constructions, figures and proofs. Also, partially supported by the programme POSC, by the Centro International de Matemtica (CIM), under the programme 'Research in Pairs', while visiting Coimbra University under the Coimbra Group Hospitality Scheme.Д¤Дћmail: - see front matter В© 2007 Elsevier B.V.

It should be used for teaching and studying geometry, but also as a major Internet repository for geometrical constructions. Our motivation is to build and maintain a publicly accessible and widely used Internet based framework for constructive geometry. Keywords: Web interfaces for proof systems, automated geometry theorem proving, dynamic geometry software. We believe that, with the help of all its users it will become an important Internet resource for geometry. GeoThms is a publicly accessible system with a growing body of geometrical constructions and formally proven geometrical theorems. In this paper we describe GeoThms functionalities, focusing on the interface solutions required for a system aimed at supporting studying and teaching geometry via Internet. The GeoThms users can easily use/browse through existing geometrical content and build new contents.
