An isosceles trapezoid has one rotational symmetry, which is a 180-degree rotation. This means that if you rotate the trapezoid by 180 degrees around its center, it will look the same as it did before the rotation. In addition to this, it has line symmetries, but regarding rotational symmetry specifically, there is only one.
An ellipse has rotational symmetry of order 2.

Every Trapezoid has 4 angles.An isosceles trapezoid has 2 acute angles.?
A seven-pointed star has seven rotational symmetries. This means it can be rotated in increments of ( \frac{360^\circ}{7} ) and still appear unchanged. Each of these rotations corresponds to one of the seven points of the star. Therefore, the total number of rotational symmetries is equal to the number of points.
