Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.
There are infinitely many axes of symmetry in mathematics.
12 * * * * * A dodecagon need not have any lines of symmetry. It can have 1, 2, 4 or 12 lines of symmetry.
a rectangle has 2 axes of symmetry
A square has 4 axes of symmetry.
It has 5 axes of symmetry
A regular pentagon has five axes of symmetry.
An isosceles triangle definitely has three axes of symmetry
A polygon need not have any axes of symmetry. It can have at most n axes where n is the number of sides that the polygon has.
A dodecagon need not have any lines of symmetry. It can have a maximum of 12.
2 axes from angles to angles
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.
