What equation will express the relationship between the number of side, s, and the number of lines of symmetry, l, in a regular polygon

To express the relationship between the number of sides, s, and the number of lines of symmetry, l, in a regular polygon, you need to understand the properties of regular polygons.

A regular polygon is a polygon with equal side lengths and equal interior angles. The number of lines of symmetry in a regular polygon is equal to the number of sides it has.

To find the equation that relates the number of sides (s) and the number of lines of symmetry (l), you can use the formula:

l = s if s is even,
l = s/2 if s is odd.

If the number of sides (s) is even, each side of the polygon can be folded to create a line of symmetry. Therefore, the number of lines of symmetry is equal to the number of sides.

If the number of sides (s) is odd, there are no lines of symmetry that can bisect all the sides. However, there are lines of symmetry that bisect every other side. In this case, the number of lines of symmetry is equal to half the number of sides.

In summary:
- If the number of sides (s) is even, the equation is l = s.
- If the number of sides (s) is odd, the equation is l = s/2.

So depending on whether s is even or odd, you can determine the equation to express the relationship between the number of sides and the number of lines of symmetry in a regular polygon.
