Yesterday, they created shapes with rotational symmetry. They decorated the lines of symmetry with glitter after they had drawn them. Today, they created trapezoids, parallelograms, etc. with small pieces of wrapping paper. Our tree is starting to look great! Of course, it is symmetrical, too. A figure has rotational symmetry if it can be rotated around a point so that resulting figures match the original figure. The point around which you rotate is called the center of rotation, and the smallest angle you Equilateral triangle The order of rotational symmetry of an equilateral triangle is three.not only are the opposites sides parallel, they are also congruent; opposite angles are congruent; and the diagonals of a parallelogram bisect each other. A parallelogram has 180° rotational symmetry around the point of intersection of the diagonals—the center of rotation for the parallelogram. This creates a foundation on which to build a more complex understanding of symmetry at higher levels of the curriculum, e.g. the order of reflective symmetry and rotational symmetry.
