The flag of Ukraine has 1 line of symmetry.
None.
Just one.
It has no reflection symmetry because the white diagonal lines are thicker on one side than the other.
There are NO lines of symmetry because the image in the center CANNOT be devided in any direction and be mirrored. The REST of the flag might be fine that way, but because of the SEAL, its has 0 lines of symmetry. Any image you want to find symmetry for must be MIRRORED in some directions, and we are talking about ENTIRE images if they say flag, its the ENTIRE flag... so no matter HOW simple the line art of the flag is, if there is ANY complicated image that is not MIRRORED on both sides then THAT cancels the symmetry entirely.
the British flag has no lines of symmetry it only has a point of symmetry (in the middle of the flag)
The flag of Jamaica has 2 lines of symmetry.
one vertical line of symmetry.

The Japanese flag has four lines of symmetry. Two of them are a horizontal line halfway up the flag, and a vertical one halfway across the width. It also has two rotation lines of symmetry across the diagonals.
