But there is a geometry with the angle as its only basic notion, called . geometry; it is much less known than metric geometry. Its “isomorphisms” are the conformal (i.e. angle信徒 发表于 2025-3-23 15:28:26

Fabio Sartori,Riccardo Melen 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
