A regular hexagon with six equal sides has six lines of symmetry. For all regular polygons, the number of lines of symmetry is equal to the number of sides.
Know MoreFor regular polygons with an odd number of sides, each line of symmetry bisects one angle and the side opposite. For regular polygons with an even number of sides, the lines of symmetry alternate between bisecting opposite angles, and bisecting opposite sides. It is possible to construct irregular polygons that are symmetrical, but no irregular polygon can have as many lines of symmetry as a regular polygon with the same number of sides.
Learn more about ShapesCircles have an infinite number of lines of symmetry. Any line that bisects a circle through its center is a line of symmetry. Circles are the only Euclidean shape with this property.
Full Answer >A regular pentagon has five lines of symmetry. An irregular pentagon, with non-equal side lengths and internal angles, may or may not have any lines of symmetry.
Full Answer >A regular heptagon has seven lines of symmetry. Each one runs from a vertex to the opposite side, bisecting the side at a 90-degree angle.
Full Answer >A rhombus has only two lines of symmetry. A rhombus is a four-sided, two-dimensional shape, also called a diamond, that falls under the category of quadrilaterals. Its sides are the same length, but angles are not 90 degrees.
