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.
An arrowhead shape typically exhibits rotational symmetry of order 1, meaning it looks the same only when rotated by 360 degrees. It does not possess any rotational symmetry at smaller angles, as rotating it by any degree less than 360 will not align it with its original orientation. Thus, while it has symmetry in its overall shape, it lacks multiple rotational symmetries.
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.
The order of rotational symmetry of a 2D arrowhead shape is 1. This means that the shape can only be rotated about its center by 360 degrees to look the same, as it does not match its original position at any smaller angle. In other words, there are no other angles of rotation (like 90 or 180 degrees) that will make the arrowhead appear unchanged.
A trapezium, a kite, an arrowhead, a quadrilateral with 4 different sides. In fact, anything other than a parallelogram (and its special cases).
A trapezium does not have rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
A trapezoid has no rotational symmetry.
Equilateral triangles have rotational symmetry.
