A decagon need not have any but the default number (1) of rotational symmetry. It can have rotational symmetry of order 2, 5 or 10.

How many lines of symmetry. does a irregular decagon have?

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.


How many line of symmetry in the decagon?

A regular decagon has 10 lines of symmetry. Each line of symmetry can be drawn through a vertex and the midpoint of the opposite side, as well as through the midpoints of two opposite sides. This symmetry reflects the decagon's equal angles and sides, allowing for multiple symmetrical divisions.
