Yes.
Yes rectangles and parallelograms have rotation symmetry. rectangles and parallelograms have a rotational symmetry of 2. I hope this information helps you.
Parallelograms - including special cases.
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.
A trapezium does not have rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
A line has rotational symmetry of order 2.
It has 8lines of rotational symmetry
A trapezoid has no rotational symmetry.
Equilateral triangles have rotational symmetry.
It has rotational symmetry to the order of 2
No a Z doesn't have a rotational symmetry
It has line symmetry (straight down the center) but not rotational symmetry.
