- Is it possible to construct it without trigonometry or analytical geometry?
- Is it possible to show that it cannot be done without trigonometry or analytical geometry?
- (Regrettably) I tried to do it via solving some trigonometrical equations, then I realized I am getting nowhere. So, how would I approach with trigonometry?
Note 1: In the actual drawing, $c=6$, but that does not matter, obviously.
Note 2: I am not looking for
