OK Geometry download

Version 19.1.1 (Windows)

Released on 04.June 2022

What's new?

Thanks to Ercole Suppa for helpful suggestions and comments.

Version 19.1 of OK Geometry consolidates the three modules that were developed in minor versions after version 18.2. All three modules are now included in Plus mode of OK Geometry.

The first module is the Advanced Query module. It allows to relate a given object of a construction with objects derived from other objects of the construction. In this way, we obtain a hypothesis of how to construct this object from other objects in the configuration. 

The second module is the Generic Constructions module. It allows the creation of families of constructionally isomorphic dynamic constructions that can be observed all together at once.

The third module, Observing Algebraic Formulae, observes algebraic relations between geometric quantities in a dynamic construction.

Several new triangle objects have been added to the Triangle module.

The documentation has been partially rewritten and supplemented, as have the provides example files.

Changes from the version 18.1.10

  • A considerable part of the documentation was rewritten.

  • Some terminological changes were introduced in the Advanced Query module. Also, the auxiliarx objects (Y) are now listed at the beginning of the list of queried properties.

  • The Observe algebraic formulae module has been significantly improved. The terminology used in the module has also been changed.

  • The Generic mode of work no longer exists. It is now part of the Plus mode.

  • The OKExamples directory of examples has been reorganised and significantly expanded.

  • A new reporting scheme (mosaic) has been added.

  • The ->S button for adding scenes (in Plus mode) was removed.

  • Many triangle objects (triangle centres, circles, conics) have been added.

  • Some minor bugs have been corrected

    See the Delta file for more details.

Previous important versions

Version 18.1.2. (Windows)

Released on 30.June 2020

What's new?

  • Significantly Improved module for exporting constructions and the report of a project.
  • Updated and improved documentation. The translation to Czech is also updated - thanks to Irena Strausova!
  • An F1 button (call to Glossary) is added in Editor Menu (Plus mode). The Glossary (F1) now considers the construction commands as well as explanations.
  • Improved command for labelling points, conforming icons, copying icons.
  • Improved module for expressing numbers as radicals.
  • User can at any time choose between the exact ot perturbed mode of  displaying configurations.
  • The display of found properties can be restricted to those involving a specified objects. It is possible to set the level of restrictions.
  • New triangle centres and bicentric points added.

A more complete list is in OK Geometry delta file.
Note. OK Geometry requires no installation. Just unzip the unloaded zip file to some directory and run the program OkGeometry.exe

Version 17.2.2. (Windows)

Released on 05.January 2020

What's new?

Thanks to Ercole Suppa for many helpful suggestions in this and some previous versions.

  • Changed the appearance and the functionality of the blue dot that controls the two modes of representation (exact and perturbed mode).
  • The glossary and command index and the triangle index  now show information from documentation, including the path to the commands. Furthermore, the command can be called from the glossary.

  • Added several new triangle centres and other triangle objects.

  • Significantly improved Editor help system, both in commands glossary and in help widget. Also added a visual help for Shapes and Check commands

  • The form for remodelling objects is significantly improved.
