the answer is 12 or 5 it is all how you look at it............
A regular pentagon has five axes of symmetry.
In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.
3
i think 5
0 if it is irregular, 8 if it is regular. Probably some numbers in between are possible, too.
It has 5 axes of symmetry
Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.
A regular pentagon has five axes of symmetry.

A heptagon has seven sides, so a regular heptagon has seven lines of symmetry (they run from each vertex to the middle of the opposite side).
Order 7 if it is a regular heptagon; otherwise Order 1.
