Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
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).
No.It is regular because it has at least one line of symmetry

Koalas have bilateral symmetry, as all vertebrates do.

Ah, the beauty of symmetry! An oval has an infinite order of rotational symmetry because it looks the same no matter how much you turn it. Just like nature's wonders, the oval's graceful curves bring a sense of harmony and balance to our world.

No, eggs are ovals. An ellipse has two axes of symmetry; an egg has one axis of symmetry. An ellipse is a special case of an oval. The word oval actually comes from the Latin for egg (ovum) Technically speaking, although the egg is oval in two dimensions, it is a 3D object, and is thus called an ovoid; an ovoid is an oval in three dimensions
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.
2 how to you not know that?Actually the answer is "one or more" - how do you not know that?
