Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
The letters H and Z have both line symmetry and rotational symmetry
F has no symetry : line or rotational symmetry
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
A sphere has rotational symmetry of an infinite degree.
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.
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.
