You cannot. You cannot ensure the lines are strictly parallel using only a ruler.

Parallel
For that period of time, d(t) (the distance) is not changing so the motion is zero velocity.
A parallel motion board is a drafting table accessory used in technical drawing. It consists of a ruler mounted on a track that moves horizontally and vertically, allowing for precise, parallel lines to be drawn on the drawing surface. This tool is commonly used by architects, engineers, and drafters to create accurate drawings and designs.

Longitudinal waves occur where the motion of the medium is parallel to the waves.
Some examples of parallel motion linkages include the Scott Russell linkage, the Peaucellier-Lipkin linkage, and the Watt parallel motion linkage. These linkages are commonly used in mechanical systems to ensure that two points move in parallel to each other.
