The line of reflection in symmetry is the imaginary line that travels down the line of symmetry. For example, in a square, the line of reflection would be the line down the center of the square, and the line down the diagonal of the square.
Because the diagonal line is not generally its axis of symmetry unless it is a square
It has a line of rotational symmetry - along the diagonal.
yes
No.
If you had a circle and you halved it, exactly in the middle, then that line would be a line of symmetry! And it is the same with a square. If you halve it exactly in the middle then that would be called a line of symmetry! And then all the lines of symmetry in a square are down, across, diagonal from the left and then diagonal from the right! But in a circle there are LOTS of lines of symmetry!

If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
The diagonal of a square for instance is a simple line of symmetry
