A figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.
A circle and square.
Line
Many figures. For example, an ellipse.
You turn it a quarter to see if it still has a line of symmetry.
A line has 180 degrees rotational symmetry.
yes
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
z
A circle and square.
Line
Many figures. For example, an ellipse.
You turn it a quarter to see if it still has a line of symmetry.
A figure has rotational symmetry if you can turn it about a figure.
The letters H and Z have both line symmetry and rotational symmetry
It has line symmetry (straight down the center) but not rotational symmetry.
A line has rotational symmetry of order 2.
A line has 180 degrees rotational symmetry.
