2.1 The symmetries of a parallelogram, an arrow and a rectangle. A parallelogram has two-fold rotational symmetry around its center. We will denote the two-fold axis with a vertical “pointy” ellipse (Fig. 2, left) and with the number 2. An arrow is symmetric by reflection of a line through its middle.
3 Αυγ 2023 · A shape is said to have a rotational symmetry if after its rotation of anything less than 360°, looks the same. This rotation can be clockwise or anticlockwise. Geometric shapes like equilateral triangles, squares, pentagons, hexagons, or any other regular polygon posses rotational symmetry.

Symmetries in physics are typically expressed by mathematical groups acting in some speci c way on some objects or spaces. In the rst chapter we introduce the basic notions of group theory using the
Rotation symmetries. An equilateral triangle can be rotated by 120 , 240 , or 360 angles without really changing it. If you were to close your eyes, and a friend rotated the triangle by one of those angles, then after opening your eyes you would not notice that anything had changed.
Rotational symmetry is defined as a type of symmetry in which the image of a given shape is exactly identical to the original shape or image in a complete turn or a full angle rotation or 360° rotation. It exists when a shape is turned, and the shape is identical to the original.
Rotational Symmetry. Basically, a figure has rotational symmetry if when rotating (turning or spinning) the figure around a center point by less than 360º, the figure appears unchanged. The point around which the figure is rotated is called the center of rotation, and the smallest angle needed for the "spin" is called the angle of rotation.
