a line of symmetry is the middle of a shape that is the same on both sides
It is a median.
To have no symmetry the four sides would all have different lengths, and each angle would also be different. The figure would not look like a square or a rectangle, but would instead be an irregular 4-sided polygon.

Well, honey, numbers like 11, 88, 69, and 96 have rotational symmetry because they look the same when flipped or rotated. Just like a good martini, these numbers are perfectly balanced no matter which way you turn them. So, if you're looking for a numerical twirl, those are the ones to go for between 100 and 1000.
Yes is a rotational symmetry 180 degree it will look like these

they are the same
Something that you can fold and its equal....
Symmetry exists naturally. Look at an animal, a leaf, or a flower and you will see symmetry (one side looks like the mirror of the other).

Because the London Eye can turn a full 360 degrees and replicate or look like itself it considered to have rotational symmetry.
It's just when you rotate a shape. Each time you rotate it, and it looks exactly like the shape you had before you started rotating, is one line of rotational symmetry.
