What's that, EUKLID DynaGeo ?

EUKLID DynaGeo is a Windows program about geometry. It lets you create dynamic drawings i.e. drawings that allow to move (some) objects without losing the interdependences of the geometrical objects established during the preceeding construction:

a perpendicular bisector will always stay a perpendicular bisector,
a line segment joining the points A and B will always run from A to B
a parallel line will always stay parallel,
.....

For example, if you have correctly constructed the circle through the three points of a triangle, then this circle will always run through these 3 points, no matter how you drag the edges of the triangle! The following picture shows an example of an EUKLID DynaGeo drawing:

With EUKLID DynaGeo you can...

...create all the standard geometric objects: points, lines, segments, circles, polygons...
...use the built-in standard constructions: perpendicular, bisector, perpendicular bisector,...
...use the built-in standard mappings: reflection, translation, rotation, dilation,...
...measure distances and angle widths
...calculate and watch expressions
...colour the objects in your drawings

For the advanced users there are more interesting features: you can...

...create trace lines, even dynamic ones!
...create macros to shorten often used detail constructions
...copy your drawings to the clipboard in EMF or BMP format
...export your dynamic drawings into web pages

...and much more to discover by yourself!
