It has a line of rotational symmetry - along the diagonal.
Axis of symmetry.

No, line symmetry and diagonal symmetry are not the same. Line symmetry, also known as reflection symmetry, occurs when a figure can be divided into two equal halves that are mirror images of each other across a line. Diagonal symmetry, on the other hand, occurs when a figure can be divided into two equal halves that are mirror images of each other across a diagonal line. In essence, while both involve symmetry across a line, the orientation and positioning of that line differ between the two types of symmetry.
All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).
no.
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
