Webb10 apr. 2024 · If we examine the order of rotational symmetry for a regular hexagon then we will find that it is equal to 6. A regular hexagon has 6 equal sides and can be rotated at an angle of 60 degrees. The angle of Rotational Symmetry The angle of rotation is the smallest angle a shape is turned or flipped to make it look similar to its original shape. The special cases of 2D (wallpaper groups) and 3D (space groups) are most heavily used in applications, and they can be treated together. A rotation symmetry in dimension 2 or 3 must move a lattice point to a succession of other lattice points in the same plane, generating a regular polygon of coplanar lattice points.
