List the angles of rotation, separated by commas, less than 360° if the figure has rotational symmetry. if
the figure does not have rotational symmetry, enter the number zero.
the list of angles of rotation is

The list of angle of rotation is zero

Step-by-step explanation:

* Lets revise some definitions about isosceles trapezoid

- An isosceles trapezoid is a trapezoid with congruent base angles

- An isosceles trapezoid has congruent legs

- An isosceles trapezoid has 1 axis of symmetry

- An isosceles trapezoid has no rotational symmetry

* Lets solve the problem

- From the attached figure:

∵ The figure is quadrilateral

∵ The quadrilateral has only a pair of parallel sides

∵ The parallel side not equal in length

∵ The other two sides of the quadrilateral are equal in length

∴ The quadrilateral is an isosceles trapezoid

∵ The isosceles trapezoid has no rotational symmetry

∴ There is no angle of rotation

∴ The list of angle of rotation is zero
