Question

An 'n'-sided regular polygon has ___ lines of symmetry.

Answer 1

A regular polygon has as many lines of symmetry as the number of sides it has. So, an 'n'-sided regular polygon has 'n' lines of symmetry.
For example, a square is a four-sided polygon having four lines of symmetry.

Here, 1, 2, 3 and 4 are the lines of symmetry.
