GAME POINTS AND LINES We have not gone on Laynlandii and Flatland. And there is a special reason. Even if there are no inhabitants, is itself a direct and very real plane! Upon reflection, what about the symmetry on the line. With two matches we can very easy to imagine two possible cases. (Some aspects of this situation, we have already discussed earlier.) Matches may lie head to one side. Then they are easily combined. Alternatively heads (or tips) to each other. In this case, on the line there is a point in which the mirror can be placed in such a way that there will come a seeming combination of match with his reflection. In other words, on the line there is a center of symmetry. We have to imagine that the mirror is gone in at one point and it reflects the half-line segment. In mathematical reasoning it is quite possible.
