The first point you click on is the one that will be mirrored. Then you can click the line or the second point.

Rotate a point around another point. The angle will taken from a already constucted angle. The first point you click on
is the one that will be rotated and and the second point is the center of the rotation.

Move a point. Click on a point that you want to move and then on a vector that defines the movement.
