Problem: How many lines of symmetry are possible for a 27 sided polygon?
One example of a 27 sided polygon:
What is a polygon? What is an n sided polygon? Here we have n = 27.
What is meant by line of symmetry? How could an image symmetric to a line be constructed?

Can you answer the question for n = 4? . . . n = 4? . . . n = 5? n = 6?
Note: A polygon does not have to be convex.
Construct a 27 sided figure with 0 lines of symmetry.
Construct a 27 sided figure with 1 line of symmetry.
