No numerical 7 has no lines of symmetry or 'mirror image'
A heptagon can have 7 lines of symmetry but it need not have any. It will have 7*(7-3)/2 = 7*4/2 = 14 diagonals.
It has 7 lines of symmetry
A heptagon can have 0, 1 or 7 lines of symmetry.

In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.
There is no such word as a "hepticgon". A heptagon can have 0, 1 or 7 lines of symmetry.
In general, a regular n-gon has n lines of symmetry (for odd n, each line goes through a vertex and the side opposite; for even n, half the lines go through two opposite vertices and half go through two opposite sides). A regular heptagon has 7 lines of symmetry. It has 7 symmetrical lines
