Yes.
Yes, a regular pentagon has rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
It has both because it has 5 lines of symmetry and rotational symmetry to the order of 5
it is order 5
F has no symetry : line or rotational symmetry
Yes
Yes, a regular pentagon has rotational symmetry.
No - a pentagon has 120 degree rotational symmetry.
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.
They have not got any rotational symmetry
5
The letters H and Z have both line symmetry and rotational symmetry
It has both because it has 5 lines of symmetry and rotational symmetry to the order of 5
It has line symmetry (straight down the center) but not rotational symmetry.
A line has rotational symmetry of order 2.
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
A line has 180 degrees rotational symmetry.
