Rotational symmetry counts how many times a shape will fit onto itself when it is rotated 360°.
When an oval (I assume you mean an ellipse) is rotated it will fit onto itself after 180°, thus it has rotational symmetry (of order 2).

Yes, an oval does have rotational symmetry. An oval has an infinite number of lines of symmetry passing through its center, which means it can be rotated by any degree and still look the same. This is because an oval is a type of ellipse, which has two axes of symmetry - a major axis and a minor axis. Rotation by any multiple of 180 degrees will result in the oval looking unchanged.
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
A trapezium does not have rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
It has 8lines of rotational symmetry
yes it does. It a rotational symmetry of 3
2
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
An oval typically has two lines of symmetry, which means it has an order of rotational symmetry of two. This means that the oval looks the same after a 180-degree rotation. The center of rotation would be the point where the two axes of symmetry intersect. The oval does not have any other rotational symmetries due to its asymmetrical shape.
Are you referring to the Marquise Cut in Diamond jewelry? This is in the shape of a pointed oval; it would two-fold rotational symmetry.
A trapezium does not have rotational symmetry.
yes, it has a rotational symmetry of 180 degrees, and of course 360. like if you flipped it upside down, then put it on top of the other one it would look the same. just not a lowercase.
The letters H and Z have both line symmetry and rotational symmetry
It has rotational symmetry to the order of 2
It has 8lines of rotational symmetry
Equilateral triangles have rotational symmetry.
A trapezoid has no rotational symmetry.
No a Z doesn't have a rotational symmetry
