The first claim of Justine is incorrect and the second claim of Justine is correct and this can be determined by the definition of line of symmetry and by finding the angle of rotation.
Given :
A regular hexagon ABCDEF with center at O.
For a regular hexagon ABCDEF, lines of symmetry are the lines that join the opposite vertices and perpendicular lines on the opposite sides of the polygon through point O.
Therefore, the first claim "The only lines of symmetry for regular hexagon ABCDEF are the
lines that contain one vertex and O" is incorrect.
The angle of rotation is given by:
[tex]\rm = \dfrac{360^\circ}{Number \; of \; sides}[/tex]
[tex]\rm = \dfrac{360}{6}[/tex]
= [tex]60^\circ[/tex]
Therefore, the second claim of Justine is, "The only angle of rotation that shows rotational symmetry is 120°" is correct.
