Begin with a line segment on the paper and fold the paper so that the segment's endpoints lie on top of each other.
Step-by-step explanation:
We know that a perpendicular line segment is formed with the help of paper folding in following steps: Draw a line segment on a paper. Fold the paper so that the endpoints of the line segment are on each other. The crease that is formed on the paper and pass through the line segment is the perpendicular line to the given line segment. The point on the line segment is the mid point of the line segment. Hence, option: A is the correct answer.
