Geometry and dynamics I: billiards, that oscillate. They move about at constant velocity unless there is a collision, either at an endpoint or in encountering each other. The conditions in case of collision are these: when the particle on the left encounters the wall on the left at 0, it rebounds with the same speed and of course in

Here we need only recall: two distinct points uniquely determine a line that contains them, along with a segment that joins them; two distinct lines intersect in a single point, with the sole exception of parallel lines.
