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.
A circle, square, and a triangle all have rotational symmetry.
No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
Yes, 180 degrees. In the degenerate case that the parallelogram is a square, then 90 degrees.
The square has 4 sides and has rotational symmetry of order 4.
The square has 4 sides and has rotational symmetry of order 4. Also, the angle rotation measurement is 90 degrees.
A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.
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.
A circle, square, and a triangle all have rotational symmetry.
It has rotational symmetry of degree 2 or, if it happens to be a square, of degree 4.
