3 Lines of symmetry
it has data that displays lines threw the segement
The description given fits that of parallel lines
Do you really need five lines when this really fits.
A square or a rectangle fits the given description
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
causes & effect of earthquaks of 25 lines information
Bohr model explain these spectra.
Two lines will remain parallel when they are intersected by a transversal line
