When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't

How do you tell if something has rotational symmetry?
A figure has rotational symmetry if you can turn it about a figure.
What figure that does not have line or rotational symmetry?
z
What figure does not have rotational symmetry?
a right triangle
Can a figure with two or more lines of symmetry can have rotational symmetry?
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
How many lines of rotation of symmetry does a square have?
Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
How do you tell if something has rotational symmetry?
A figure has rotational symmetry if you can turn it about a figure.
What figure has rotational symmetry?
A sphere has rotational symmetry of an infinite degree.
If a figure has rotational symmetry does it have line symmetry?
yes
Is it true that a figure with no lines of symmetry have rotational symmetry?
yes
How do you know if a figure has rotational symmetry?
Visual inspection. It's usually pretty obvious.
How many orders of symmetry does a rectangle have?
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
What figure has rotational symmetry but not line symmetry?
A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.
Can a figure have line symmetry and not rotational symmetry?
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
What figure has a rotational symmetry?
a circle or a sphere
What figure that does not have line or rotational symmetry?
z
What figure does not have rotational symmetry?
a right triangle
What figure has both line symmetry and rotational symmetry?
A circle and square.
