Shapes can have an infinite number of sides, but one example with a large number of sides is the googolgon, which has 10100 sides. Other examples of shapes with a large number of sides include the chiliagon (1,000), myriagon (10,000) and megagon (1,000,000).

A dodecagon is a two-dimensional shape with 12 sides. A regular-shaped dodecagon has all its sides with the same length, and all internal angles are the same size. An irregular-shaped dodecagon has sides and angles of different sizes.
