How many lines of symmetry does a guitar have? - Answers

A normal acoustic guitar body (ie the general shape of a guitar; without strings, body-finger protector, ornamentation, etc) would have 1 line of symmetry running down its centre. Strung, it would have no lines of symmetry as the lower strings are thicker than the higher strings, but if the thickness of the strings is ignored, it would still have 1 line of symmetry. A lot of Guitars have no line of symmetry as there is a "cut-in" into the body near the bottom of the neck on one side to allow easier access for putting fingers onto the fret-board on the higher notes (the frets closest to the hole). Similarly, electric guitars often have knobs for various controls which are placed to one side again making the guitar asymmetric.
