sorry i dont know thats why im asking
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
Along the length of the arrow, probably 2 - possibly 3. Otherwise there is no rotational symmetry.
An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.
A kite, An arrowhead, an isosceles trapezium are three possibilities.
It has 8lines of rotational symmetry
The order of rotational symmetry of an arrowhead is 2. This means that the arrowhead can be rotated by 180 degrees and still look the same as its original position. Additionally, it can also be rotated by 360 degrees, which represents one full rotation. Thus, there are two distinct orientations (0 degrees and 180 degrees) where the arrowhead appears unchanged.
A trapezium does not have rotational symmetry.
A trapezium, a kite, an arrowhead, a quadrilateral with 4 different sides. In fact, anything other than a parallelogram (and its special cases).
The letters H and Z have both line symmetry and 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
