Point groups in two dimensions are mathematical concepts used in the study of symmetry in two-dimensional objects or systems. A point group is a collection of symmetry operations (such as rotations and reflections) that leave a geometric figure unchanged when applied. These symmetry operations involve rotating, reflecting, or translating the figure, but in the context of point groups, we mainly focus on operations that keep the center of the object fixed.
