A dodecagon need not have any lines of symmetry. It can have a maximum of 12.
A square has 2 pairs of opposite parallel lines.
There cannot be parallel lines in any [plane] triangles.
there are 2 sets of parallel lines in a square
A diamond has two pairs of parallel lines.
A regular dodecagon has six pairs of parallel lines.
A dodecagon has 12 sides, and the number of lines of symmetry it possesses depends on the specific characteristics of the shape. A regular dodecagon, where all sides and angles are equal, has 12 lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. Irregular dodecagons may have fewer lines of symmetry, determined by their unique properties.
