Which figure is most likely to have more lines of symmetry?

The hexagon is a shape that typically has more lines of symmetry than the other options provided. A regular hexagon, which has all its sides and angles equal, has six lines of symmetry. These lines can be drawn through opposite vertices or midpoints of opposite sides, allowing for multiple ways to fold the hexagon such that one half matches the other perfectly.

In comparison, a triangle, depending on its type (equilateral, isosceles, or scalene), has fewer lines of symmetry—an equilateral triangle has three lines of symmetry, an isosceles triangle has one, and a scalene triangle has none. A rectangle has two lines of symmetry (one vertical and one horizontal), and a regular pentagon has five lines of symmetry.

Given this understanding of symmetry in geometric shapes, the hexagon stands out as the figure with the most lines of symmetry, making it the correct answer.
