Geometry constructions

A mouse click will draw a point and add it in the history. To draw a segment, push the mouse at the first vertex, move it and release it at the second vertex. To move a point (and all constructions depending on this point) click on the point, then push the mouse again on the point and move it, release it at the new position. To cancel a move, release the mouse outside of the graphic area.

Example :
Push one mouse button, move the mouse, release the button, you have drawn a segment : the system will define in the history 2 points (A and B) and the command to draw a segment between these 2 points. Do it again from one of the two points, the system recognize that you pointed from one known point. It is therefore easy to draw a triangle, draw the last segment. Know click on A, and move A with the mouse, the figure should follow.

Other constructions (e.g. circles, conics, special triangles, ...) are made using commands that are in the Geo menu.
