7 have rot
Lines of SymmetryAn equilateral triangle has three lines of (rotational) lateral symmetry: one extending from each vertex to the midpoint of its opposite side.An equilateral triangle has 3 lines of symmetry3. Each bisects a vertex and perpendicularly bisects the opposite side.
In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.

7 have rot
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
H, I, N, O, S, X, Z
Order 7 if it is a regular heptagon; otherwise Order 1.
A cube has 3-fold rotational symmetry, meaning it can be rotated by 120 degrees and still look the same. It does not have 5-fold rotational symmetry because the cube's faces are not oriented in a way that allows for that type of symmetry. The angles between the faces do not align with the requirements for 5-fold rotational symmetry.
There are no right angles in an octagon.An 8 sided octagon normally has no right angles.

no, unless you draw it funny with a really long line on the top and split it diagonally at the point.
No numerical 7 has no lines of symmetry or 'mirror image'
