2. If the dotted line on the trademark paper is oblique, then the incision is a parallelogram.

If the left and right sides are cut along a straight line, they must be parallel to each other.

3. If the dotted line on the trademark paper is randomly drawn, it will be crooked when cut, at least it is an axisymmetric figure.
