Interactive geometry: all the way, from the very beginning to competitive level problems -- more than a hundred of them, and we keep adding.

We'll lead you, problem by problem, on a thoroughly planned route designed for the most exciting and effective exposure to the landscape of classic geometry. Every task relies on the previous ones for context -- you'll never meet complexity while unprepared.

Ruler and compass at the base, that grows into a rich palette of convenient
derived tools, which allow for compact expression of even the most complex solutions. The most involved constructions will gain a lot of clarity from use of the rubber tool, that helps to remove intermediate details that are no longer essential.

Dynamic variation of the givens -- literally, movement of given lines, segments and constituent points -- raises the interactivity to a new level, allowing you to discern geometric reality from a phantom hypothesis, with a single move.

Still, any possibly correct solution will be recognized and accepted as such -- regardless of the way you achieved it -- no solution is pre-defined. That way you can be sure that a rejected solution is a wrong one.

The free constructions screen will allow you to detach from the initial context in favor of experiments and hypotheses, and more so -- to employ backward constructions, based on a supposed solution, which often allows you to find the missing link.

The most complicated problems could be rather hard to solve without hints, which are made available in a step-wise manner, so you can take just what you need, and nothing more.

Engage your attention, logic and imagination, experiment with never ending
interest, stay involved with the game since the beginning and to the very end.

Discover geometry from an unexpected angle.
