A parallelogram - including rhombus and rectangle - has 180 degree symmetry. A square has 90 deg.
It has rotational symmetry to the order of 2
A regular nonagon with 9 sides has a rotational symmetry of 9.
Rotational symmetry of order 1.
A line has 180 degrees rotational symmetry.
They have not got any rotational symmetry
The quadrilaterals that always have both line symmetry and rotational symmetry are squares and rectangles. Squares have four lines of symmetry and rotational symmetry of order 4, while rectangles have two lines of symmetry and rotational symmetry of order 2. Other quadrilaterals, like rhombuses and parallelograms, may have one type of symmetry but not both. Thus, squares and rectangles are the only quadrilaterals that consistently possess both symmetries.
Parallelograms - including special cases.
The answer depends on the quadrilateral. Some have rotational symmetry or reflective symmetry and it is not possible to distinguish between these and translations.
A quadrilateral with a rotational symmetry of order 4 is one that can be rotated 90 degrees, 180 degrees,270 degrees, and 360 degrees onto itself. The most common examples of such quadrilaterals are the square and the rhombus. In these shapes, each rotation results in the same appearance, demonstrating their high degree of symmetry.
