You can find a parallel line to a given line using the paper folding technique.

Yes this is true.

Explanation:

Suppose we are given a straight horizontal line that is drawn in the middle of the page and we have to find the parallel of this line. We can easily fold the lower end of the paper horizontally, keeping it parallel to the drawn line. We can easily draw a line using the folded lower end of the paper. In this way we can draw a parallel line.
