An irregular decagon has no lines of symmetry. Unlike a regular decagon, which has 10 lines of symmetry due to its equal sides and angles, an irregular decagon lacks uniformity in its shape, meaning that it cannot be divided into identical halves by any line. Therefore, it generally has zero lines of symmetry.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
