Symmetries in regular polygons (http://www.cimt.plymouth.ac.uk/projects/mepres/book8/bk8i15/bk8_15i3.htm)
Look at the regular heptagon below. A heptagon is a shape with seven sides and this one has equal sides and equal angles. You can see that there are seven lines of symmetry, and the regular heptagon also has rotational symmetry order seven.

Does a regular heptagon have reflection symmetry?
Yes.
How many lines of symmetry does a regualar heptagon have?
It has 7 lines of symmetry
How many lines of symmetry for a heptagon?
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).
What is reflectional summetry?
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
How many lines of reflection symmetry does the letter S have?
None - it has rotational symmetry - not reflection symmetry.
