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 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.
Oh, dude, an oval has an infinite number of lines of symmetry, so technically it has infinite rotational symmetry. But like, who's really gonna sit there and rotate an oval forever just to prove a point, right? So, yeah, infinite rotational symmetry for the win!
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
