ruler
The pair of undefined terms used to define parallel lines is "line" and "point." Parallel lines are defined as two lines in a plane that do not intersect, regardless of how far they are extended, and a point is used to describe the position relative to these lines. These terms are foundational in geometry, serving as the basis for more complex definitions and theorems.
Set squares are useful for drawing parallel lines and perpendicular lines.
parallel?? Parallel is usually used to talk about lines or similar it means they are equal distance apart. For example railway tracks are parallel.
A parallel motion ruler is a drafting tool used to maintain a consistent distance between two lines while drawing. It consists of two arms connected by a pivot point, allowing the user to move one arm while the other remains parallel to it. This mechanism ensures accurate and parallel line drawing, making it especially useful in technical drawing, architecture, and engineering applications. Its design helps improve precision and efficiency in creating parallel lines and measurements.
That's commonly known as a "straight edge".
In construction, all you need is a compass and a ruler.
A straight edge or a ruler are used to construct straight lines.
parallel lines are used in the white house. The columns holding it up are parallel lines and the floor and the roof of a room are parallel planes as long as they are the same shape
Protractor
The instrument that is used to construct straight lines is called a rule. Often people make the mistake of calling it a ruler, but its a rule.
A straight edge or a rule are used to construct straight lines. Laser line setter, In some cases a plumb line
you can coordinate parallel because parallel lines never touch or cross
Lines parallel to the equator.

Corresponding angle are used to prove if lines are parallel. If they are congruent then the lines cut by the transferal are parallel.
They are lines of latitude.
