Which quadrilaterals always have both line symmetry and 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.


What quadrilaterals have rotational symmetry of order greater than one?

Parallelograms - including special cases.


How do you find a sequence of rigid motions for quadrilaterals?

The answer depends on the quadrilateral. Some have rotational symmetry or reflective symmetry and it is not possible to distinguish between these and translations.


What quadrilaterals have a rotational symmetry of order 4?

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.
