A trapezoid has no rotational symmetry.
None
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It does have rotational symmetry of order three.
A parallelogram has rotational symmetry of order 2.
A trapezoid has no rotational symmetry.
None
A trapezium does not have rotational symmetry.
A "pure" trapezoid (a pair of parallel sides and two random sides) does not have rotational symmetry. If it is a parallelogram then it has a 180 degree symmetry. And if the paralloelogram happens to be a square, you have 90 deg symmetry.
no
It has only 1.
0,one full turn doesn't count as a rotational symmetry
A isosceles trapezoid for example.
Yes, an isosceles trapezoid does have rotational symmetry. An isosceles trapezoid is a quadrilateral with two parallel sides of equal length, which means it can be rotated around its center by certain angles (180 degrees, in this case) and still look the same. This is an example of rotational symmetry, where the shape can be rotated and still appear unchanged.
How about an isosceles trapezoid
A line has rotational symmetry of order 2.
