No a Z doesn't have a rotational symmetry
A trapezoid has no rotational symmetry.
It has line symmetry (straight down the center) but not rotational symmetry.
No A rectangle has rotational symmetry as well
It does have rotational symmetry of order three.
A sphere has rotational symmetry of an infinite degree.
a circle or a sphere
A sphere has one point of symmetry (at its very center) if one considers rotational symmetry in its three dimensions. If one is only considering reflectional symmetry, it would have an infinite number of lines of symmetry.
A trapezium does not have rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
It has 8lines of rotational symmetry
It has rotational symmetry to the order of 2
Equilateral triangles have rotational symmetry.
No a Z doesn't have a rotational symmetry
A trapezoid has no rotational symmetry.
A line has rotational symmetry of order 2.
It has line symmetry (straight down the center) but not rotational symmetry.
