i am not sure but i think a trapezium has 1 order of rotational symmetry
A scalene triangle has one order of rotational symmetry.
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
