A rectangle has at least one line of symmetry. Specifically, it has two lines of symmetry: one that runs vertically down the middle and another that runs horizontally across the middle. Other shapes, such as squares and isosceles triangles, also possess lines of symmetry. In general, many shapes can have one or more lines of symmetry, depending on their properties.
