You could rig up springs with the right coefficients, but that's cheating. You could demonstrate Pi and then derive e from it, but that's unsatisfying. You could could iterate triangles based on the ratio expansion, but that's an approximation.
Of course, in the end a geometric method can still only define it as precisely as the precision of the tools available, in our world.
