Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It does have rotational symmetry of order three.
A parallelogram has rotational symmetry of order 2.
parallelogram * * * * * A parallelogram does have rotational symmetry (order 2).
It has 1 order of rotational symmetry.
I think it has 2
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 ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
A line has rotational symmetry of order 2.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
It has rotational symmetry to the order of 2
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.
If it is a regular octagon then it has rotational symmetry to the order of 8
It does have rotational symmetry of order three.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A parallelogram has rotational symmetry of order 2.
if you mean rotational symmetry then yes, rotational symmetry of order 4
