If a regular polygon has 16 sides, how many lines of symmetry can it possibly have?

The possible line of symmetry that a regular polygon of side 16 has is:

16

Step-by-step explanation:

The relationship that holds between the number of line of symmetry and the number of sides in a regular polygon is:

Number of lines of symmetry in a regular polygon is equal to the number of sides of the regular polygon.

Here we are given that a regular polygon has 16 sides.

This means that the number of line of symmetry in this given regular polygon is:

16
